system already does kick out inactive players on unity chat, iirc even kicks while I'm still moving but never use chat channel.

And it already has capped daily DI point reward, which is 100 (& 200 for Mireu, which is already a very rare encounter since I never saw it during my return campaign). Reasons ppl might still be spamming them due to bead farming & they even capped at 50k, which is exact amount needed to start aeonics & even if somehow gather another 50k, it'll be useless since one needs to finish working on whichever aeonic they started in which one has to defeat all escha NMs (which I heard a must redo on whenever picking another aeonics to work on), or abandon to work on new ones. Heck... I'm even surprised finding out that I capped my beads this return campaign & having muled my thoughts on what aeonic I should be getting & asking alot of opinions on LS & finally decides to pick BRD instrument since many responses favours toward that.

Last I played, participation already dwindled down in about 2 hours since daily reset, hence it should be quite leeway to reach next DI location without reduced waiting time from 10 to 5 minutes. Of course, this is on my server Bahamut, can't really speak for others like Asura, or Ragnarok in OP's case. & as others said, it is that easy to get full participation. There's one time my THF barely made in time when DI NM almost dead & only delivers like one hit & still get either full 100 or just 80, which is easy enough to get another on next DI, which always has fixed rotation in order of Zitah > Ruaun > Reisenjima.
