The morning drops only recently started lasting >5 seconds since like March, which indicative of less demand/crowds at the parks, somewhat of a "slow" period.
At this point I think the only reason the VQ is being kept for Tron is due to ILL. It usually sells out everyday, which is a good thing. However you could also look at the inverse and see that the return times for ILL is usually within an hour, which could also indicate there isn’t much demand for it. If they remove the VQ, does that hurt or help ILL sales? Maybe they don't want to pull the trigger and stick with the status quo for now and wait for an actual need to switch it (TBA).
I do think that once TBA opens, Tron will lose its VQ and go to standby. But I've said this a couple times before for GOTG: CR, and that still has VQ..
SDMT has higher ILL demand and sells out faster for the day than Tron. Due to this, I believe Tron will move to Genie+ and SDMT will stay as ILL along with TBA. It will also boost G+ sales during the off-season (like right now) imo..
