As somebody who intends to switch distro over this: it's not addition of the field.
It's the reason behind the addition: in-advance compliance with laws with limited geographic scope and no actual implementation details.
Plus absolutely the utter and complete dismissal of all critiques by the systemd people.
Basically this poisoned the trust on the maintainers ESPECIALLY because it's such a "minor" change.
No reason to get the user angry if it's something "you just can not use".(and the presence of other PII is not the gotcha they think it is)
The insistance means it's either ego, malice, or both.
(I'm going with "ego": the person responsible for this first suggested it on twitter, got people telling him don't do it, and went and did it anyway)
I'll also add this was the straw tha broke camel's back for me(never been the biggest systemd fan).
