We're just adding a mechanism for easy personal code deployment and
modularization, not a cure for broken code.  If there's a load order
conflict the user will have to figure it out, just like putting loads in
the wrong order in the .emacs file.

I'm sure users can use that (I will).  But they can also specify the
order with explicit loads if that's what they need.

That's, again, overengineering the problem (as Mark Twain put it, "with
all the modern inconveniences").
