There have been sharp disagreements as to whether or not this
separation is a good idea for unrelated variables, or whether one
would want to share between some clients/terminals/sessions or not.
No agreement could be reached.  Being able to _switch_ will make it
possible for users to work with both approaches, with multiple use
patterns and requirements.  We can then meaningfully poll them at one
point of time.

Which is pretty much what my proposal is supposed to achieve: preserve
the old behavior.  It is just that I also have taken the step of
proposing a plan how to fix the multi-tty part of the breakage.
