Future of SourceType - Call For Consensus?

At the moment, we have 3 bugs that touch on SourceType, listed here:


Reminder: SourceType is this enum:

enum SourceTypeEnum {

At the moment, we have no part of the spec that depends on this - the 
only thing you can do with it is to read the attribute on a track, and 
ask for specific types via a constraint (which is useless for "none", 
and only has a single possible value for video and audio tracks).

It's been suggested as a future extension point (such as specifying "I 
want a screen capture"), but experience with future extension points is 
that it's very easy to get them wrong unless you already know the 
extension you want when you design them.

We've had very little comment on the bugs so far - so I'm trying for a 
call on the list:

***Proposal: SourceType should be removed from getusermedia version 1.0.***

If we don't hear anyone arguing in favour of keeping it for a week (July 
11), we'll take that as permission to remove (there's always the 
possibility to reinstate).

If we get arguments ..... we'll take it from there.
