Comment:

 I do agree.

 I always run:
  macchanger -r --another eth0

 Unfortunately if I forget to do so, or if the connection fails, the system
 takes the permanent MAC back.

 Furthermore it should be nice if the mac were chosen among a good set,
 where by "good" I mean "compatible" with the used HW

 Ticket #10969 (an old one) says:
 «It's well understood that your set of guard nodes can act as a
 fingerprint.»
 Well, currently I always connect to the very same guard node (which is a
 safe one, btw)
 Can anyone pls clarify this point?

 None the less, may be somebody is behind a router or a wan, so even
 changing his local Mac, wouldn't be enough to mask him...
