It's not unprecedented, and probably a decent chance it'll be implemented within 24 hours if they find it necessary. But, as long as they believe their AFK timers are working, probably not. And, very likely the game considers players active if they're using external programs to automate movement or whatever, so the game and devs have no visible way to accurately determine if inactive players are clogging up the servers.
In short, it might happen, but, with everything visible on the back end, they may determine it doesn't seem necessary.
Personally....... I think, maybe, I might suspect, given how quickly queues drop off later at night, the AFK timers may genuinely be sufficient. Sure, probably some getting around it. But I'm not sure a daily reset would actually solve anything the way some players want.
