Compatibility with the NFS protocol.  A google search on "nfs 16
groups" returned a lot of hits.

You can raise the limit, but you need to make sure that you raise it on
all servers that share NFS mounts.  If you don't you may end up with
remote file access either failing or not passing the full group
membership list to the remote server, which could cause incorrect
"permission denied" errors.
