The comment here is certainly out of date now.

But I think keeping these xfs_bump_ino_vers2 calls around everywhere is
wrong to start with.  xfs_iread should make sure all inodes are version
1, that allows to kill xfs_bump_ino_vers2 entirely, and probably also
simplify xfs_ialloc a little more.  At the point we won't have to deal
with v1 inodes anywhere but in xfs_iread, and we can have a big fat
comment in that place why we even bother with the v1 inodes, because
the fact that we have the hasnlink bit but inodes might still be old
format is something we'll all have forgotten about in a few years,
and new developers will never figure out by themselves.
