I think the big attraction to the userfs solution was that the protocol was very simple and it was trivial to add new filesystems. From what I recall NFS isnt exactly a trivial protocol and people doing nfs<->userfs could find it rather intimidating and confusing.
In the CDROM-XA situation though, its probably better to add support for it in the ISO9660 driver directly as it doesnt require a new filesystem, just detect Mode2 sectors and deal with them properly.
