I do worry that if, at some point, we do get rid of the nfs4 filesystem
alias then we may find ourselves in trouble if we have a large base of
mount programs out there that translate '-t nfs -overs=4' into '-t
nfs4'.

I think that if you want to go down this path, you should somehow ensure
that the resulting program is capable of passing '-t nfs -overs=4' down
to the kernel (perhaps a configuration file option?).
