For the record, it is of course a requirement that all frameworks 
build on top of the same foundational runtime.

So, you can have a core standard library without a GC runtime, 
and on top of it have an expanded (compatible) runtime with GC.

So you need cooperation on runtime-profiles in addition to having 
a small focused core standard library.
