I of course don’t know Apples intentions, but what you are describing 
is the behaviour of early iOS 14 beta versions. However this behaviour 
has changed in later beta versions and the released iOS 14.0 version to 
have a random Mac per ESSID and not change that over the lifetime of the 
device (at least no so far on my devices at home), which I think is more 
in line what the rest of the industry does.

So long
