Does SUBSCRIBE_NAMESPACE return your own ANNOUNCE's

[afrind]

In moq-chat, a subscriber does an ANNOUNCE for their namespace and a SUBSCRIBE_NS for a level higher prefix. Should the relay filter these announces, or forward them back to the originator?

If it does, does it increase the potential for infinite loops, #556 ?

Individual Comment:

I'm inclined to say a client should not be able to SUBSCRIBE to it's own tracks at a relay, though I had to temporarily allow this to interop with @suhasHere. In a similar vein, I think it's best to not return ANNOUNCE messages back to the originator. They really ought to know, and if we disallow self-subscribe, it's unclear what the use case is.
