I believe this was introduced by:
commit c5901cebcabc966dd65f70080feec79bb26b4645
Author: Edward Hervey <edward.hervey at collabora.co.uk>
Date: Wed Jul 18 15:24:00 2012 +0200
decodebin: Block on caps event
A caps event is also used to establish that a stream has prerolled.
Without this, we end up allowing negotiation queries to fail, ending
in decoders (and other elements) to not be configured right from the
start with the most optimal settings.
