We do?  How and when did we decide that?

What were the arguments pro and con - where can I find the
discussion?  Did we poll the users, to get their take on this?

Since when do we advertise bindings for that reason?  Can you
point to a case where we've done that?  An advertised binding
is typically used to ensure that the simplest or most flexible
binding gets advertised, instead of a more complex binding that
the tools would otherwise automatically report as "the" binding.

At any rate, it's that intention to "change that at some future
point" that I haven't seen discussed or decided.

And that I disagree with.  But if it _has_ been discussed and
decided then I have no problem supporting the decision, even
if I disagree with it.

Oh come on.  Sure, you _could_ exit with a key that you bind
to a function that does whatever nutty thing you like, and
then have to move back where you were.  This is 100% beside
the point (seems like arguing for the sake of arguing), since
there are other keys (e.g. RET) that do _not_ take you all
around Robinson's barn.

No, my question is why _should_ we change these bindings?

Your answer is that they were changed because we decided to
change them.  Sheesh.  How about an argument to support the
change and the intention to remove these Isearch bindings?
How about polling the users?

Precisely.  So why the need for this change?  That's the
question (still unanswered).

No, that's exactly what this thread is about.  I started
the thread, and that is what my question is: _Why_ should
we change these bindings?  Reasons, please.

You seem to be content to say that the "reason" for the
change is that Juri made the change - he decided that it
should be made and he made it.  That's the starting point
for the question; it does not answer the question.
