If this is the case, then the current v5 proposal of returning a number of devices still makes sense from a discoverability standpoint. Does that make sense?

It would *almost* be sufficient.  It is useful to know if a specific
device (one that you remembered previously) is present so that you can
ask for the right one, though chaining constraints could be enough,
direct knowledge is easier if you want to avoid many-layered
constraint build-up.
