As I said before, the question is not whether addresses are MAC-derived
or randomized, the question is whether they are trackable/linkable and
at the same time exposing personal information (they do not need to be
mobile to do this).
I believe in this case a short paragraph of explanation why this is not
the case should suffice.

Grüße, Carsten
