That's a good point. Pluses in the URI scheme are permitted, but
don't have a defined meaning, so they are part of the IANA
registration, eg subversion specifies both svn and svn+ssh as possible
schemes:
https://www.iana.org/assignments/uri-schemes/prov/svn
It might be nice to allow
nbd+ssh://ssh.example.com
but that leaves an open problem about how you specify the NBD port
number (not the SSH port number).
