I'm not sure I understand your question -- the new proposed PML would
be different than CM: it would have matching and support more than one
underlying device (e.g., more than one MTL).

Could this just be CM with some run-time parameter enabled?
Possibly. Is it worth it? I'm not sure -- CM is nice in that it's so
small / simple. Do we really want to make it more complex?

All of this is speculation / vaporware at the moment anyway -- just
tossing around some ideas...
