I think this makes sense, and would be sane defaults for Wi-Fi
adapters. I'm editing todo/macchanger to make it clear the Wi-Fi
usecase is special, with a pointer to this discussion.

What do other think?

Can we agree on this (quoting what I just added to the ticket):

The Wi-Fi usecase is a bit different: the public / private computer
distinction does not make sense, but there are two main situations:

  1. Some Wi-Fi networks restrict access to a list of known MAC
     addresses, so in this case, the user of a known computer wants to
     use their real MAC address.
  2. In most (all?) other cases, we want to anonymize the MAC address.


?

If we have thought of it previously, then I did forget.
Thanks a lot for the suggestion!

So would I. Are you volunteering?

I agree. One more reason for you to volunteer? :)
