Any such "opinion" about the future, or the belief that we can
somehow predict one, would be wrong anyway.  So I am not sure
soliciting more voices to look into crystal balls would help all
that much.  Having said that...

The default rebase-merges behaviour may be improved, but changing it
in a totally backward incompatible way _without_ a carefully prepared
transition strategy will be very unlikely, simply because existing
end users would not allow us to.  I do not offhand know if the
configuration variable(s) you propose would serve as a good mechanism
to help such transition.

Thanks.
