NFSD is a client of filesystems (it uses their services). It has
certain special needs beyond the needs of VFS (the other client of
filesystems).

It it not about which instances of filesystems should be exported. It
is about which types of filesystems should be exportable. Certainly
the sysadmin decides which actual filesystems should be exported. The
programmer decides if hir filesystem is exportable. ext2fs should be.
procfs shouldn't. It might be nice if FAT32 could be, but it is hard
to implement reliably.
Maybe I should have said "should be exportable" rather than the more
vague "it makes sense to export".
Does that address your issue?
