Don't know but I'd guess

Oh heck yeah it would rule cause if it works on stock it would rock on custom

but I don't know and really just guessing cause may be I'm overly hopeful to see TWRP possibly back cause I misssssss it so very much from my Samsung galaxys S7 days with Superman ROM (ultimate ROM Ive ever used thanks)

But someone more knowledgable will say for sure if/when the time arrives ..... Until then I'm all in on the page refresh/reload since it's my new home page now !!!!!

Might even keep this device another couple of years of this works out cause I about gave up.... Any way good luck and huge thanks to everyone's efforts and contribution here

The fstab;

For example:
So in the example you posted, this particular ROM is f2fs?

Edit: @Lossyx nevermind, I read the deprecation thing better. fbev2 for sure. Thanks. Can both sdcardfs and fbev2 be used at the same time?

I have not properly tested everything, once I've done it I might make a new thread.
Your twrp indeed decrypts oos11 fine but I can't get it to backup data using same twrp to USB OTG or internal SD--all other partitions backup fine. I can browse and access, alter, copy, delete internal sd and data fine with twrp file manager. Just can't backup. See twrp logs (backup attempts at end of logs). "createTarFork() process ended with ERROR: 255"

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    #include <std_disclaimer.h>
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you.

    - TWRP boots;
    - Fastboot boot is working;
    - Decryption is working (except for Oxygen OS);
    - System, Vendor and Product partitions mount is not working but it's not a big problem;
    - You can flash ROMs;
    - Format Data is broken;
    - You can flash magisk

    Install guide (Reccomended):
    Acutally seems oneplus (or directly android 10) re-introduced the recovery partition so you should only flash it in recovery partition or you can try to boot it from fastboot. For now only boot it.
    To flash:
    fastboot flash recovery_a twrpname.img
    fastboot flash recovery_b twrpname.img

    To boot:
    fastboot boot twrpname.img

    If you have some problems with backup, like 255 error or something similar please check this guide: https://forum.xda-developers.com/oneplus-6/how-to/255-error-twrp-backup-restore-999-t3801632
    For the Bacups use always "system_image" and "vendor_image" instead of "system" and "vendor".

    TWRP 3.3.1-25 for OnePlus 7T, 7T Pro (hotdog unified) by mauronofrio:
    - Removed decryption at all for now (actually after decrypted the rom is not more able to decrypt anymore, so you have to format data to boot a rom).
    - System, vendor, product and odm mount is working.
    - Magisk is flashable, so people can use TWRP to flash magisk.
    - Rom flashing is a bit broken, the process start but at the ends it breaks at all super partition and then you have to restore the rom with msmtool, so for now is disabled.
    - Basic functions are working.

    TWRP 3.3.1-43 for OnePlus 7T, 7T Pro, 7T Pro 5G (hotdog) by mauronofrio:
    Fixed Decryption on custom roms (still broken on Oxygen OS);
    Added unified script;
    ROM flashing is working;
    System, vendor and others logical partitions can't be mounted (it's not a problem for the others things);
    Magisk and kernels can be easily flashed;
    Fixed TWRP flashing, now you can flash the TWRP directly in the recovery partition from fastboot.

    I want to thank the testing group for their continuous work
    @mauronofrio I see that last commits on Gerrit are devoted to decription. Does it mean that you're closer to classic version which all of us wait for?

    Fixed a problem of ROM flashing, now you should be able to flash all ROMs.
