I'd ask you to consider things very carefully indeed before adopting
such a policy.  It is minor changes like these, a very great number of
them, that have made Emacs as usable as it is.

Sometime, fire up Emacs-21, and compare with a modern Emacs just how
usable it isn't.  Perhaps even more dramatic, fire up XEmacs.  I predict
you would find it irritating, and the things that would irritate you
would be just the lack of the little improvements that you are proposing
now to object to.

For example, in XEmacs, the C-x 4 bindings split the screen with the
windows above eachother, which is suboptimal on a modern wide screen.
Yes, it's nothing earth-shatteringly bad, it's just not quite right.  If
you do a batch-byte-compile, the error and warning messages are partially
drowned out by low-content messages about "compiling foo.el" and "Writing
foo.elc".  Again, nothing you can't get around, but Emacs doesn't do that
any more.  These are just two of the many, many, marginal improvements
Emacs has made in the last decade or so.

I don't think we should stop making these small improvements.
