Is that so rare? For me it's pretty standard that the core modules _have_ 
to be loaded as object files, interpreting them would make things orders of 
magnitude slower (100× - 1000×), they'd be unusably slow.

So in my opinion it's absolutely essential that modules can be loaded as 
object files.

And that too, if it's no longer the default.

But with it not being the default, I could live well.
