Hi Christian. Some comments/corrections:

1) On servers privacy extensions are *not* always enabled. As I pointed out in comment #24, if NM is not in use, privacy extensions are only enabled for userspace-created interfaces such as "vlan123". It is *not* enabled by default for physical interfaces such as "eth0". This is inconistent, but at least it's a good default for most people (i.e., those that are using "eth0").

2) The old bugs #176125 and #841353 concern themselves with the potential leak of information of the user's MAC address. While this was a valid concern in the past, it no longer is. This is because (as I also pointed out in comment #24) NM will by default use RFC7217 interface identifiers. These do not contain the MAC address. Additionally, they will change when moving between networks, preventing tracking.

3) Finally, which has been pointed out by others earlier in the thread, even RFC4941 itself recommends that privacy extensions are disabled by default.
