That is an interesting question - SMB3.1.1 is extensible (ie negotiate
and tree connect contexts)
so in theory it shouldn't be required to add a new dialect every few
years anymore, but my
bigger reason for this is to **strongly** emphasize SMB3.1.1 due to
some VERY useful security
features in it (and eventually for the ability to do POSIX extensions
to Samba etc.).  Many
people probably don't know the advantages of SMB3.1.1 and I wanted to
hammer that
point home in this era when everyone seems to be worried about CIFS
security holes and
forgetting the excellent work that was done on SMB3.1.1 (even beyond what was in
SMB3).
