I am seeing more people with souls lately. At first I thought it was possession by lyran outliers because they have black cat features, but I'm beginning to think these are the new walk-ins. Yuuka (or someone) did saw a while ago that the new humanity was ready to have souls inserted, the hivemind has had enough training to function. That would mean there will be a shift very soon, because it's not allowed to mistreat the new humanity in the least. The old will simply have to step aside for them.
