I don't see any need for the artificial boundaries you might get with
a plugin, whatever that might look like.  ppc-opc.c already supports
multiple incompatible powerpc cpu implementations, including ones that
depart significantly from current powerpc ISA documentation.  Your new
SVP64 design is not an orphan in that respect.  I do not want to see
"plugin" silliness out of fear of stepping on OPF's toes.

The fact that some cpu is supported in ppc-opc.c has no bearing on ISA
direction.  The binutils project doesn't have that power, nor should
it.
