I argued "--except should trump everything" earlier, but the case
involving --not
--branches --except maint --not master
to mean the same as
--branches --except maint master
just does not make sense.
An alternative would be that --not would divide the command line
arguments into ranges within which one --except would subtract
subsequent refs from earlier globbing arguments in the same range.
That's not simpler to explain than your current proposal.
So I like the relative simplicity of this approach. Here is a bit of
documentation.
