Halo Reach Multiplayer Matchmaking Community Maps for Team Slayer

Will 343 Industries put new Community Maps on the Team Slayer Playlist Since they are in charge of the Matchmaking Maps from now on (Bungie announced That on the Bungie App) ?

& will there be the same game types?

I would also like to see some in Living Dead and Invasion. Bungie had that forge contests for all gametypes, yet they never put any in those two. Some of the maps they did put into any multiplayer from the forge contest were unbalanced too.
