Hi, all,

I'd like to add one point.

This doc gives guidance on creating minor versions, but never addresses
major versions.

IMO, past variants of NFS have not handled major version changes
appropriately. Each one has been assigned a new port number. This is no
longer recommended practice (see RFC7605, Sec 7.5).

Is this issue addressed in another document?

AFAICT, if (when) NFSv5 is developed, it seems to appear to need another
port number. If that's the case (and I sincerely hope it isn't), it MUST
be the last one assigned to this service.

Joe
