Using a system where the user account data comes from a database (ldap, ...) instead of a plain file might be a valid use case even for system accounts.

Especially when they need to have the same userid across different machines.

I used to do this for the sudo group in some setups.

In that case, those unit files should depend on the databases being started first and should be re-parsed at that time. It gets a bit ugly... you need to parse the unit files once to get dependencies and not care about unknown users at that point, but care about unknown users when you actually go to start the service. I think it's manageable, though.
