For the best reasons about why this has been removed, you should probably
poke David, but there are some reasons I can come up with:
1) It's kind of a quirk. A user using GStreamer for the first
time will probably not expect this.
2) It does not really make sense for filtercaps.
3) It was part of gst_caps_intersect, where it definitely does not belong.
gst_caps_intersect should be symmetrical.
4) It does solve issues while it raises others. Adding pixel-aspect-ratio
would not be possible for example if that behaviour still existed, because
you could never have a source plugin without PAR and a sink plugin with
PAR that way.

I'm sure there are better reasons though.
