There are surely environments where a larger NGROUPS is used and wanted.
Linux allows up to 64k groups.

A small extension (like 32) would be trivial to do (just bump the value)
and might show issues that we have and would also allow to develop
and test extensions for NFS.

A larger extension needs changes to the data structures. You don't
want to move 64k gid_t arrays around.
