Use LOS 19 (better LOS for microG) but think about to migrate.
Offical maintainer is afaik Linux4.
He has dedicated opinion about TWRP (which is part of /e/):
Is there any TWRP I can use for this ROM? No, we don’t support TWRP. Why is it not supported? TWRP usually mounts data and modifies the files in there. On OTA over Updater it could happen that TWRP messes up the encryption policy so data won’t be able to decrypt anymore and you will lose your files. As we want to avoid such things, we simply don’t support it. Other reasons? Imo TWRP is way too feature overloaded. Also, data partition isnt supposed to be mounted in a recovery anyways. TWRP also doesn’t format data properly at default and just “wipes” (removes all stuff exp data/media) it, which will cause issues on roms which use different encryption method or filesystem.
I am wondering is he right? Arn’t data protected with /e/ if device gets lost or anyone else access it via TWRP? Create and steal a backup? Or is he wrong?
