If you finally decide to implement full difficulty levels, of course that would be great. But it seems like more work. What I proposed is simpler: Leave the current food respawn as "Short" and make it the default option, and then add the Medium or Long options in the menu (totally optional) for those who want a greater challenge, without needing to change anything on the leader boards. In any case, and whatever you decide, it is a real pleasure to share these thoughts with you, and that you are such a nice person :-)
