Don't know if it's enough of a reason for you to reopen this bug, but we might
have some reasons for videotestsrc/audiotestsrc to keep being a URI handler:

* internally we already have an element (a simple wrapper around uridecodebin)
that, using `gst_object_set_properties_from_uri_query_parameters`, controls the
videotestsrc and audiotestsrc elements for test cases. For example, we can use
a URI "videotesrc://?num-buffers=100&pattern=7&is-live=1" to simulate a
non-infinite live source. The testsrcbin would have to copy all these
properties to be a drop-in replacement for us.

* the internal wrapper element also has an "audio" and "video" gboolean
property that prevents exposing ghost pads for any audio/video srcpad resp.
from uridecodebin. As such, this will also clash for us a bit. It's not a major
issue and one that we can solve with a workaround, but will be a minor headache
nonetheless.

That being said, testsrcbin seems to be also something very useful for us (we
might be able to automate audio/video sync issues with this), but separately
from videotestsrc/audiotestsrc.
