I have now commited that. Happy to merge an updated version should add
the other profiles.

ALSA currently does support that and given that the high-level stuff
PA wants to do is generally a subset of what ALSA allows you to do in
theory the question is how far this could ever go.

That's data read from the USB device itself. PA uses that only if no
prettier device string is available in the usb.ids database (which is
the same one that is used by lsusb).
I can only encourage you to submit a nicer USB string to the usb.ids database:
That way evryone can enjoy nicer strings.
