`forward-paragraph' presently returns "0" if the number of steps given by

     ;; Return the number of steps that could not be done.
Which makes it similar to forward-line.

IMHO buffer-position reached is a more useful return value.
Which you can get with (point).  So what's the point?


Having a consistent design meeting expectations.
For example a function designed to move point should return new position.

Then people may write functions taking already the return value.
Thats more nice than writing FORWARD (point).

Presently return values of move functions are not regular. Some return nil or t, some positions IIRC, this
one it's remaining loop variable.

Well, would consider re-write efforts and not suggest that now for skip-char functions.
In case of moves over paragraphs its easily done.
