Yes. But truthfully this is a small issue. The bigger issue is that an
application cannot perform a copy without knowing what "type" of
capability it is copying. It needs to know this because the copy
behavior depends on the capability type.

Notice that this is not the same as the interface type, and it
introduces a significant application complexity.

Note further that not all reply capabilities are invoked by a reply.
Some are invoked by a send or a call!
