It's unlikely there is anyone using that or even if they are they have bigger problems than this patchset :). After all, v0 was introduced 9 years ago and it was already conditionally compiled by the time BTRFS was merged in the upstream kernel. The patches themselves are really simple - patch 1 removes all the code within ifdef guards. Patch 2, in turn, ads graceful handling by aborting transaction where it makes sense or calling btrfs_handle_fs_error and printing an informative error message.
