Eh, in pihole mac or ip address is a valid way to add a device to a group so you can give it a different policy. I have multiple access points but they’re not meshed so if I randomized I’d have to have multiple client entries for a single device. Or turning off randomization for my trusted networks means just 1 client entry.
Are you okay? They asked a very specific question and you’re coming in with answers that don’t matter.
When did I say anything about dhcp or mention randomized mac being a silver bullet for privacy? Your opinion on how effective it is or isn’t has nothing to do with the fact that they can turn it off for their network and it will solve the issue they’re asking about.
