I would prefer using `M-s .` for consistency (even if it requires
changing the command name). In swiper it works like that and it is very
comfortable and consistent with the "expected" experience; but I
understand that someone will complain for sure... (as usual)

So without any other alternative, `M-s M-.` will be good enough. In
general it would be better (for consistency) if we "reserve" `M-.`
"suffixes" for future thing-at-point-or-region commands right?

With the interactive experience in mind I think this could make sense as
it does in `ivy-thing-at-point`.

In my opinion from the api point of view, the important modification
could be the method to know the "kind the thing" detected after calling
the function (region, word, symbol, url) but also a function to get the
bounds instead of the text (like bounds-of-thing-at-point-or-region).
