Sorry, I don't see any problem.  This is normal and expected behavior,
and one more buffer cannot possibly be a problem.  Especially since
that buffer will be created soon enough anyway, once you load some
previously-uncompiled package.

I fail to understand why another buffer could be a problem.

I don't see any bug here.
