DLC in Matchmaking

I was playing Invasion with a couple of friends recently when the unexpected happened: Tempest, a map from the Noble Map Pack, showed up in the vote options. It didn’t win the vote unfortunately, but its appearance is still significant for me personally because it marked the first time in literally years that I have seen a DLC map show up in any non dlc-specific playlist outside of Score Attack. My question is this: now that all of Reach’s DLC is free, should 343 update all of the playlists to require players to have the map packs installed so that there’s a higher chance of those maps appearing in lobbies? I feel like there are still a lot of casual players who just aren’t aware that they can download these maps for free.

From memory doing something like this requires an actual update to Reach and if so, not something I think they have capacity to do at the moment
