The rest of R&D to MaRo: *crying motions*
Every time they print a card that pulls a limited selection of stuff from exile or a contextually-useful color pie break in a Commander deck, an angel gets its wings.
As much I would love them to, I don't think they'll do a BFM card just because it would be a rules nightmare.
A BFM type mechanic is something that's a 100% certainty over a long enough time horizon; it's got obvious splash appeal, and it's simple enough to understand at a basic level that it won't be a problem to put in packs. Ultimately the rules manager's job is to find ways to make the stuff Design/Development come up with work and this type of mechanic is the sort of thing that, once it made it into a near-final file, they'd push very hard to see specced out and printed.
(None of that speaks to whether this is the specific place they do it, of course.)
