It's up to someone arguing for a change to Emacs
to make an argument in support of that proposal.

Please make an argument for Emacs to sacrifice
those specific keys to default bindings.

Users have always been able to bind any keys.
That in itself is obviously not an argument for
binding any particular key by default.  And if
you were to suppose it were, then it would be an
argument for binding _any_ and _all_ keys by
default.

You need to present arguments in favor of binding
these keys by default to those specific commands.
The burden of argument/proof/convincing is on
whoever is proposing a change.  Just "Why not?"
doesn't cut the mustard.
