This change makes sense to me.
The "return 1" made me think about the return value a bit more. If we
want to replicate the behavior of getent from glibc, we should return
2 if the user/group does not exist or if the passwd/group files are
missing. I don't think any ebuild/eclass code really cares about the
specific status though, so we can leave that alone for now.
