That "if supported" here is pretty problematic. There's no way to know.
Feature flag maybe?
Also, there are scan flags now. However, I don't see that this should
(ab)use the scan function. It doesn't seem likely that you want to do
this while you're sending probe requests, etc. OTOH, it seems likely
you'd want identical dwell times on all channels to have comparable
values, which isn't the case here.
I really think you need to decouple the API for this from scanning.
