There should be no drones in supers.

But agree rhombus/figure 8 work more efficiently.
Not really folklore. I've often carried out a demaree and then allowed them to backfill the top brood boxes with honey in strong OSR flows. I let hatching drone out every so often but the odd one persists and gets stuck when clearing. In my experience porters are a total pain, not just with rogue drones but due to slow slow clearing efficiency and malfunctioning springs as well.
