Query (not a bug): Device selection - should permissions matter?

When thinking about how to make a more formal permission handling for
mediacapture-main, I wonder about how permission status should influence

Let's think about an UA with 3 attached cameras:

A has a "granted" permission
B has no permission, so will be prompted for if selected
C has permission "denied".

If I select with constraints that allow either to be selected, what
should happen?

Three possibilities I see:

1 - Spec says "disregard C, pick between A and B at UA's choice" (prompt
if you feel like it)
2 - Spec says "choose B; if that's unsuitable prompt for A" (prefer
3 - Spec says "this is not a spec matter, UA will do what it wants" (no

All of these can be written as normative requirements or "implementation

At the moment, the spec is roughly "1" (step 3 can be seen as skipping
"denied" devices).

What do people think?
