What happened to f2fs?

This is the "Extendable Read-Only File System", so it will be used for the read-only system partitions. The user data partition will still use ext4 or f2fs.

Nothing, really.

As far as I can tell, they don't even care in the vendor test suite until you hit 12.0/13.0

EROFS is also a read-only filesystem, so there's a time and a place.

Vendors should be fine to use F2FS for user data mounts, outside of APEX. (Although those are read-only as well, so...)

Is it possible to mount EROFS as read-write, as otherwise modifying anything in system partitions will be a lot more difficult, even if you have root.

This sounds like a feature (photocopying a page from Apple's playbook), not a bug.

Nope, it's more a bug. Why shouldn't I be allowed to modify anything? I'm the owner. Sure, maybe if you unpack the image on your PC and then flash it you can modify it, but it makes it far more difficult than it could be

If you can't do it on device, that means malware can't do it either.

As long as you can do it, it's under your control.

I guess you can make a new fs snapshot to overwrite the partition. Otherwise it's impossible to upgrade system as well.
