That there are many commands bound to keys in Isearch is a plus, not a minus -
they are there to make Isearch more useful.

Yes, as in Emacs generally, more key bindings can mean more remembering.  That's
what `C-s C-h' is for.

That just means that you can do more in Isearch - a good thing.

Yes, having more key bindings means a potential downside of further taxing a
user's memory.  Tradeoff.  No different from any other mode (or pseudo-mode -
Isearch is essentially modal) that binds keys.

At any rate, this feature is not about adding any command/key bindings to the
Isearch default map.  It is about treating Isearch normally wrt a prefix arg.

And you will be able to opt out easily.  Don't you wish you could opt out just
as easily for all the other control keys that no longer exit Isearch? ;-)  At
least here all you have to do is set an option value.
