As with all of features it's about prioritization.
We'd like all of the above (and probably below) in oVirt but it's about investment in time and resources.
>From a downstream investment point of view we prioritize what we invest engineering in based on customer demand, which has been limited so far for the other browsers but it's certainly something we'd like.
Hopefully that comes from other upstream contributions, right now we're concentrating on filling gaps before adding other combinations like this but customer demand can change our investment, but again there's a community who marches do the beat of a different drum that can change all that.
