Technical goal..

In this specific use case, Windows install (that is probably not going
to happen too often over spice), it's easy (and similar to real-hw) to
switch the disc temporarily. If that's the only reason to expose
multiple CD to the users, I think it's not generally useful enough.

No, more feature is bloat. It's natural that user prefer a polished UI.

Ok, we need to find the real use case behind that feature & UI request
and discuss how to best answer it.

Maybe? I would be surprise if that's the best solution we can come up with...

It's not the reason, they use spice-gtk for usbredir. However I don't
know the real reason, probably they want to expose less devices with a
better UI.
I was simply pointing out that the spice-gtk widget is not used by all
the spice clients.
