I don't disagree, but again, this technical detail doesn't seem as a
good enough reason to change the current situation (at least not for
now). Such a change would require tracking all the instances where some
form of "xxx-at-point" or "forward-xxx" is used directly or indirectly
and change those into new logic.

Moreover, after such a change forward-sexp will behave similarly to
forward-word; useless redundancy. Now, if helps, you can think of
forward-sexping over foo$bar as if forward-sexping over ($ foo bar).
