just curious tested the rom and couldnt get root to work i know you said wanting offical status before focusing on stuff. was just wondering is smart charge and smart pixel something that might come in once official is done or is it not that type of rom?
you can try two things to get rooted the first method (patch boot.img)
1: get magisk ap from officia; github page
2: get boot.img from the extracted files from dotOS Payload.bin and saved it on download folder on phone.
3: Open magisk app and on the install button ull have the chance to choose the boot.img you transfered to download folder
4. once selected hit the "let's go button" and magisk will patch the boot.img.
5: once patching is done you can transfer the boot.img to your laptop or pc wichever.
6: once that transfer is done you have to put yor device in fastboot mode: adb reboot bootloader.
7: after doing so flash the patched boot.img with the command: fastboot flash boot <magisk_whatever_xgsg.img> (it wont be called like that obviously its just example).
8: reboot device and your done.
the second method wish has less steps is to download the same magisk.apk but change the type from apk to .zip
it will be called Magisk-v22.1.zip. with that reboot to recovery and flash it in ADB Sideload with the command: adb sideload Magisk-v22.1.zip
and your done aswell reboot and enjoy
