You are still focused or your narrow use case. Why is this only for
WiFi? Why cannot i use it for other systems using IGMP? Switches? VPN
servers? etc. We want a generic solution for all use cases, not just
some obscure niche.

And Linux does not care about commercial devices. And you would never
implement this in the driver itself, that would immediately gets
NACKed because it is not generic, but the concept should be generic.
