No, because if they didn’t use Layering, those queues would be have the word “Days” in their time. By the time layering is removed, the population will have decreased dramatically, but some servers like Streamer ones, will be over-represented still.
They want to (and promised they would) get back to a single realm with no layering “within a few weeks” of launch. That may mean a spike of queues on over-populated servers but that’ll be worthwhile to level out the population.
