I'm not convinced that the bug shouldn't be fixed instead.

Start with

So you're saying that `superword-mode' should simply add "_" to the word
syntax?  Or something else?  Sorry to be dense.

Another possibility is to make the motion context-sensitive, so we move
by word inside strings or comments but by sexp or symbol outside them.

(I actually discovered I like using `forward-sexp' with `superword-mode'
in non-Lisp languages, except through strings.  In Lisp it jumps too
much.)
