Featured Game Mode/Rotating Game Modes?

Forgive me if this is common knowledge but google was giving relevant information.

I'm someone who enjoys featured game modes; i.e. "Ultra Rapid Fire" "Doom Bots" "One For All" Add in All Random to any of these modes and I love them even more.

It seems since TFT that these are no longer running on weekends. As someone who doesn't enjoy TFT this really sucks for me.

I'm not sure if Riot plans on rotating these anymore; I understand if not. If you decide to no longer include these as a rotating game mode would custom games be an option? PBE maybe?
