Thanks.

Would you like to do it?  I think all it would take is to move the code
there, set it in prog-mode (so that modes that derive from prog-mode get
to use this new code by default) and then make a few random tests in
various major modes (mostly those that don't themselves set
fill-paragraph-function).

BTW, could add a couple tests to test/automated, to try and make
sure your use-case is remembered?
