I doubt this is a good idea.  It looks like this would break dynamic
(re)linking of pipelines.  You assume that unlinking a pad is a bad thing
because it would cause the streaming to block.  You cannot know whether this is
the case however.  I can unlink a pad and link it again (to some other pad)
immediately (while the pad is blocked of course).  This would not pose any form
of harmful delay for the  user of CollectPads.

If I understand you correctly, you propose to make CollectPads detect the
unlink and exclude the pad from the collection.  It is clear to see how this is
not what is generally wanted.  It would break dynamic linking performed on the
source pads of all muxers and cause slightly different semantics in the case of
e.g. adder.

Can you name a specific situation where the current behaviour causes problems?
