I agree with that conclusion, too.  I think it's fine that a theme
does this.  Maybe we could file a wishlist level request to add the
makunbound functionality if we think it's worth working on.

Is there anything left to discuss, or should I go ahead and push this?

Also, I think we would need Eli to decide if this should go to
emacs-27 or master.  Thanks.
