Oh, and one alternative would be to provide just one `systemd-credenentials` key
here that always refers to such a credential mapping, which has then an array
of all the credentials with their name and value.

As I checked [fdo-sc] and there are like 50 supported credentials, some with
a glob to allow sets of credentials per type like for network or udev rules,
so 15 might not cut it quite fast even if the use-case is not _that_ complex.
