Yes, but my suggestion does not introduce such a dependency.
erl_prim_loader will just apply a fun (or MFA) that it gets as
argument. There is no hard dependencies in the "wrong" direction.

Compare it with how the lists module works. The lists module
applies funs from other applications but does not dependent on them.

It seems unneccessary. What would the purpose be?
