A point to note is that we neither obsolete nor update rfc793, so if we
make a requirement as SHOULD or MUST does not cause an implementation to
go out of spec (just as in RFC3168 makes SHOULD/MUST recommendations,
but does not mean that
all rfc793 implementations are out of spec)

The whole discussion becomes relevant only if we are really updating
rfc793, so as long as you see these changes as standalone, the question
of SHOULD/MUST/MAY  become self explanatory in the right context. 

So, in that sense I propose the changes as MUST. If an implementation
claims
compliance with these changes, than this (MUST) is the way it has to be
implemented.
