Can Black Market Brawlers give Mastery XP?

I know it's a little thing, but I feel like the Black Market Brawlers mode is close enough to normal rift play that it should merit Mastery XP.

I am aware that the main reason Riot disqualifies a game mode for Mastery XP is because it does not match standard rift play style, but I think BMB is close enough that it should still count.

I am also aware that this suggestion might be coming too late because BMB is likely to go away at some point, but meh. Maybe for other game modes like it in the future?
