I guess functioneer and sysop rights should be enough to make these edits, so the edit should be safed.

Sounds like your attempted edit triggered the wikilambda-edit-predefined right, which it shouldn't have, yes. (Sorry for the low-context error message; fixing that is T351583.)

@Ameisenigel: However, I've re-created (what I imagine is close to) your edit in our test suite, and it seems to pass: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikiLambda/+/1017875 – do you have any more information about the change you tried to make?

For Z64 I tried to add the following German labels:

• Z64K1: Identität
• Z64K2: Typ
• Z64K3: Umwandler
• Z64K4: nativer Typ

I have now been able to add translated keys to Z46 and Z64.

This issue is the same as the one filed in https://phabricator.wikimedia.org/T374931

And was fixed with https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikiLambda/+/1073433

The issue is not related about the particular rights of key labels, but to the fact that the UI initializes keys Z4K4...Z4K8 when they are undefined, and those require functioneer rights. This has been fixed so that they are only initialized for people that can edit them.
