But _why_ wouldn't it be "smart"?  The command _is_ executed, it has
the normal effect (which may become relevant if the buffer-read-only
state changes), and it does _absolutely_ no harm to the buffer
contents or anything else.

You still have not presented a single case where a notice would be of
any use at all, even if just to prevent the user from wasting time or

All that you have stated so far is that you want a warning.  What for?
What help will it provide to the user?  Do you fear that a user will
spend hours toggling Overwrite mode without noticing that he can't
insert or overwrite?

Why should Emacs warn about executing a command that it can perfectly
well execute?

I don't get it, and you are not exactly making a convincing, or even
any case for it.
