Wow, long discussion!

We routinely take mite-heavy, DWV-symptomatic (showing signs of DWV such as
deformed wings and dying pupae) hives, eliminate the mites with a strong
formic treatment, requeen, and see them rapidly recover.

Ditto for when I've created "sick yards" to stock with all our sick
colonies (other than AFB, which we burn. and EFB. which we hit with OTC).
About half turn around without treatment, the rest die.  We place the
deadouts on the recovered ones as honey supers, and all works fine.

I don't want bees that I need to baby.  If they can't handle frames from
deadouts, screw 'em.  So long as we manage varroa and provide good
nutrition, we see few sick colonies, other than the occasional case of EFB
in the spring.
