Read what _I_ said, please.  I was describing the issue Jury alluded
to.

And evidently, the desire to remove it means we think its binding
outside Isearch is more useful.

You have an alternative for that.

The intent of the advertised bindings is to change that at some future
point.

No, it's "at least 2 things".  Because depending on how you exit
Isearch you may need to move point first.

That's a different issue.  You asked why the advertised bindings were
changed; you now have the answer, I hope.

There are facilities to tailor the commands that exit Isearch, if the
user doesn't like the defaults.

That's a separate discussion.
