Runtime is a bit trickier as the WPA supplicant maintains an
aggregated scan list (maintained
using ageing), so, if we change the criterion in between, we might
have to flush the existing
scan results and start afresh, hence went with compile time.

But I will think more about this (this was a fresh bug) while I await
any other feedback.
