Universal redefine queues to being an integral part of the ride experience then they invent this that makes them mostly obsolete.
I love UOR's newest queues and all and I am fortunate that have gone through on multiple occasions, but when I try and view my experience based on the line flow I am experiencing at that moment in time (trying to imagine it was my first time through), I found that often, the pacing and flow can really suck.
I think the idea isn't to Eli mate queues, but instead to greatly shorten them. For instance, if Gringotts had VQ then it wouldn't just not have a queue. The queue would be limited so the farthest it backs up is the first room without any outdoor queue. You keep the queue long enough to experience the best parts of it, but long enough so that nobody is stuck in the heat.
Dang autocorrects! Eli Mate had me going there for a minute. Anyway, I think this a lot....I still think most of this is for rides like DM, but I do not see something like this being tried with a standby queue. For, DM, I would imagine a group pre-stages in the outside queue who were all paged that their ride is ready.
I get that if you think the Disney way (fast pass1.0), you wait or you get a return time...I see this more as, 'we can get you in about an hour from know...we will let you know when you can join the queue for a 15 minute wait, so expect to hear from us in about 45 minutes...since you can't wait in the queue, but you are in a virtual queue...well, I see it as, hey, I'd rather stroll around for 45 minutes than to stand in this line.
Perhaps they could make the queues more like a walkthrough attraction that leads to the ride. FJ for example could have a tour guide that takes you through the castle other elements could even be added to make it more interesting and/or more story driven kind of like Poseidon's Fury.
I mean, I imagine this is what Fallon could be like. Have the Tonight Show Stuff as a sort of pre-show for groups who are called back to just stroll around in, a lot like all the stuff in the lobby of the monster make-up show.
