Introducing a new command raises the question how should users
navigate using the two.  Will C-M-<RIGHT> invoke forward-sexp or the
new command (or maybe one or the other in some dwin-ish way)?

What are the problems with teaching treesit-forward-sexp do what the
new command does?  IOW, why do we need a new command?
