I do not use the wheel very much too, but the occasions on which I use
it are just when I want to mark a wide region  by scrolling!

Actually, I did not realize that someone might want to:

=> mark a (small) region
=> scroll down with the wheel
=> paste the region contents previously selected

and, of course, this is just the opposite of what I normally do!

Actually, I used to raise transient-mark-mode on at emacs startup

Me too.

I am not a lisp/emacs developer, so do not know whether this might be a
good/feasible option: what about a t/nil configurable variable such as
wheel-scroll-extends-region?

thanks and ciao
