Hmm, it looks like this is already the case; if I invoke zsh as "ksh":

$ setopt | grep comment
nointeractivecomments off

And indeed the source gives interactivecomments the OPT_BOURNE flag.

The only other thing might be to also give it the OPT_EMULATE flag, but
I'm uncertain about that.  In what circumstances are you encountering
difficulty with this?
