I think it's worth answering this point separately.

There's plenty in CC Mode which isn't good, and a danger of me actively
participating in the development of the -ts- modes is that some of this
bad stuff will get transferred.  I'm surely not the best judge of which
bits the bad bits are.

In the very nature of things, there's bound to be some competition
between CC Mode and the new modes, and me being on both "sides" would be
a psychologically uncomfortable position to be in.  In the long run, of
course, CC Mode cannot "win", and I accept that.

But you've got to allow me to have mixed feelings when the project I've
put so much into over ~20 years is facing redundancy.

On top of these considerations, there was a deluge of bugs reported in CC
Mode over the autumn.  I felt my priority had to be the maintenance of CC
Mode.

Yes, in the spirit of improving them, much as I have reported bugs in
other parts of Emacs.

Yes.  Plenty of people like CC Mode, but I don't think you are among
them.  These people are likely to want to carry on using CC Mode, at
least in the short term, and to do this they need a way to switch off the
new modes.  I think you must agree with me there.  Where we differ is
that I want to make this way of restoring CC Mode's position in
auto-mode-alist easy, whereas you seem to be content that it remain
difficult.  I confess I don't understand why.
