I think the biggest problem will come from 'home' users when Samba
finally removes SMBv1 (this isn't what Andrew is proposing). The 'home'
users will not even consider using SMBv2 or 3, they MUST be able to see
the shares in Network Neighbourhood, nothing else will do.
This isn't helped by the fact that the various gui 'helper' programs do
not seem to understand that SMBv1 is going away and shouldn't be used
