I don't think you'll be able to control occasional or not.
This is a Pandora's box [1] situation. Either you open it or you don't. And having alternative languages as direct competitors to Emacs Lisp, available for interactive development, would certainly be blowing the box apart.
I wouldn't mind Scheme as an alternative, the only alternative, except I don't think I'd use it myself since I would still see Emacs Lisp as domain-superior.
Agreed on the rest, except as I said, none of that materialized from the Guile camp whilst we had plenty of that goodness emerge in core Emacs.
