@mattab I figured it may be better to use a different userId hash per site.
Eg when many websites are tracked on the same Matomo, for example in an agency, then the same userId would always have a different hash per site which may be better and further anonymize the data.
On the other side it is maybe wanted to have the same userId across sites but then they could still not use this feature and "pseudo" anonymize the userId themselves.
I have no preference whether it gets merged or not.
