Totally agree! Read about this somewhere recently, it seems like the best option for our older devices. And Yes! No notion of how to do it but perhaps some nice adventurous Dev will take up the torch.It would be smarter to build Android Oreo Go,unfortunately no I do not have the experience to do it but it is just a suggestion.
i think that someone is developing lineage 15.1 for our beloved devicehave lineage oreo for S2 9100 , and 9300????
that is for all s3 versions or only i9300 ?Looks like it's coming along nicely with a lineage-15.1 branch https://github.com/fourkbomb/android_device_samsung_midas
""Midas" is the codename for the family of boards consisting of the Galaxy S3 (GT-I9300, GT-I9305, SHV-E210K/L/S) and the Galaxy Note 2 (GT-N7100, GT-N7105)." from https://blog.forkwhiletrue.me/pages/midas-mainline/that is for all s3 versions or only i9300 ?
the device tree for s3 on los15.1 already prepeared here.but midas still not perfect which needs a lot skills to run.so no body build a rom to try…(excepet the author)Here's an update on the development: https://blog.forkwhiletrue.me/posts/an-almost-fully-libre-galaxy-s3/ It's not for Oreo development specifically but it's about u-boot and the kernel.

It's not ready for anything but booting linux. If you really want to try it out, instructions are at the bottom of the page.how to install this kernel to devices any idea about it
Try it yourself
If you're after something to tinker with, have a spare GT-I9300/GT-I9305/GT-N7100/GT-N7105 lying around, and don't really care about using anything based on the old kernel (be that LineageOS, Replicant, or the stock firmware), you can even try this for yourself. While it should be possible to go back to the proprietary bootloader, I have not tested doing so: doing this would be left largely as an exercise to the reader. It's also worth mentioning that LineageOS/Replicant will boot under u-boot with a kernel compiled without CONFIG_ARM_TRUSTZONE set, but the display will not work (probably because u-boot does not initialise the display).
