hmm this is not easy to solve without breaking things.

The factory needs at construction already the correct cr id, so we cannot read it from the uri, because this is a non static method - and if we wanted to we need the cr registry ...

Thinking about this .. the NodeAddress only needs a crId to be 100% specific, which is only necessary for cross site linking.
In most cases 90% the crId is defined by the current domain - which maps to a site - which maps to a cr in the settings.

So maybe the crId should be made optional, that we dont have to specify it in the backend all the time?
Otherwise one could "hack" into other crs:

correct:

defaultCr.mydomain.de/neos/preview?node=default_324524q3_35q52532_352525235

invalid state to access otherCr from the wrong domain?

defaultCr.mydomain.de/neos/preview?node=other_324524q3_35q52532_352525235

Discussion should continue in #4564 this was just a non working stash.
