Why doesn't the Lunar Revel 2019 Pass grant tokens for Twisted Treeline games?

According to the event page,

Per-match token payouts:

• Win on PvP SR = 6 Lunar Revel Tokens
• Loss on PvP SR = 3 Lunar Revel Tokens
• Win on PvP ARAM/ARURF = 4 Lunar Revel Tokens
• Loss on PvP ARAM/ARURF = 2 Lunar Revel Tokens

What about 3v3s? The previous Pass, Snowdown 2018, also completely overlooked TT games. I can understand hesitating with more involved projects (e.g. balance updates, VGU), but this seems like an incredibly quick fix. It gets even stranger once you realize that Riot's effectively telling TT players that Riot doesn't want their money.
