Thanks for both!

OK.

Yes, if you already have one; I wouldn't spend too much time, though,
because there are reasons why a good system for one app is not good
for another. (Emacs vs. Guile, for example.)

Yes, this is pretty much the direction we seem to be moving in now:
see my last post in the "Another load path idea" thread.

My inclination is that it is a bug if order is important, but I don't
have much experience to be sure about this yet. Do you have real
examples where ordering is important?

Can you say more about the problems you have in mind, and how you
think they can be addressed?

Thanks; it's the "Another load path idea" thread.

Yes, this is exactly the kind of case I have in mind as needing
fixing. (And I have very similar cases with my packages.)
