Yes, that may be convenient.  If I understand correctly, the minor mode
would set isearch-allow-scroll to t on enter and leave it nil on exit.
And it could expose some functions like

(add-isearch-compatible-commands COMMAND1 COMMAND2 ...)
(remove-isearch-compatible-commands COMMAND1 COMMAND2 ...)
(isearch-compatible-command-p COMMAND)

that would transparently add/remove/query the isearch-scroll property of
their arguments.

A nice side effect of this new minor mode is that the naming will make
it more clear that not every command is about scrolling (for example,
enlarge-window), while keeping backwards compatibility.

I need to think about how this feature would play with the rest of the
configuration options in isearch.  What if the user wants
isearch-allow-scroll set to 'unlimited, for example.

Opinions?
