What if a tee element is used, one branch goes to a video sink which supports
that meta, and another branch goes to deinterlacer+videoresize+rtp
payloader+udpsink elements for example?

Changing the format in the caps just because a meta is added just feels wrong
to me. The caps should describe what is really inside. Additional mechanisms
like this meta are placed on top of that. They do not replace anything.
