No. They see the VF still listed as assignable after the guest terminated
and the PF got made assignable. The PF driver unloading, however,
should trigger all VFs (which are about to disappear) to get removed
from pciback. I hope to find some time later today to look into why (if
at all) this isn't happening right now.
