Me neither.  If we have a need for a separate significantly different
traditional mode, we lose most of our advantage.  CUA-mode, IIRC,
assigns special meaning to its characters only when there is an active
selection.  It is a compromise, of course.  (I think we still are not
there with regard to consistent selection behavior where we should be,
but that's a somewhat different problem).

If what I think I understood from the CUA descriptions is correct, no
key sequences starting with C-c or C-x can be used with an active
selection.  For example, selecting an active region and using
C-c C-e in AUCTeX (inserts environment around an active region, if
there is one) would not work in CUA mode, ever.  Neither would any of
a number of minor mode bindings designed to also work on active
regions.

Which is their full right to do.  99% of all video recorder owners
learn the operation of their device only superficially, thus not
getting the full benefit of video recorders.

Still, nobody suggests that the "solution" is to make the handling of
a video recorder so obfuscate to the average person familiar with
other devices, that he will be lost without reading through an
instruction booklet.

Who is to decide that somebody being able to utilize a tool without
having full grasp of all its possibilities is a bad thing?

With all due respect, who are you to decree who should not be using
Emacs?

I am a serious programmer and other writer.  And my learning time is
not a sound investment if I can't use Emacs as an application platform
for editing functionality that I can never hope to have customers of
mine wanting to use.

So we need more changes if we want to have Emacs at one time something
which does not require turning people into hackers before they can
expect to be comfortable using Emacs.

That's ok.  Nobody expects that we will finish this task in a single
step.  And blindly enabling any mode that is supposed to make things
more mainstream-like, without assessing its drawbacks and trying to
remove them where possible, would be insane.

But such modes at least can provide a basis for discussion in what
manner we can accommodate people without a determination to completely
start from scratch before being allowed to start using a good editor.
