Shoty Snipers and Tripple Team Gone?

So what happened to Shoty Snipers and Triple Team? Did I miss something about those games being removed, are they being worked on or were they only in temporarily?
I’m kinda confused, I haven’t seen any posts regarding this or their removal.
I really liked those game modes and just curious what happened to them.

They were replaced with assault due to low pop. 343 said since the latest update that they’d play around with the playlists depending on pop/popularity.

There’s lots of threads in the Matchmaking Feedback forums about this already that you can use.
