That sounds fine.  In fact, they probably don't need to use a Relocation at all (except maybe in Leyden).  If a forward reference needs a fixup, it can use a Label.

What would invalidate current assumptions is trying to support trampoline stubs in non-nmethods.  We can cross that bridge when we get to it.
