I personally find the "search within hidden text without opening it" to
be a completely useless option, so I couldn't want to cycle between all
3 options, but only between nil and `open'.

You'll have to place it in the M-s prefix map instead, which was setup
specifically to avoid eating up more key combinations which currently
make isearch exit.

I'm not sure I'd find it useful, but I can imagine some people might
like it and there's plenty of room under the M-s prefix for such
a thing.

It is in my opinion very useful in org-mode.
