Can't we patch the existing compiler pass that copies the id to the class when no class is set, and make it throw when id is not a class?

But then it would not work if you define a manual id and make a typo in the class (although more of a niche case)

There are cases where the class is eg string for some internal services.

So we could have something like ['mailer.transport', 'createFromDsn'] at this point? (Not a reference but the service ID as is?

There are many ways one can mess up with their DI config. Validating everything adds to the compilation time. That's something we always considered outside of the scope of the compilation step.

#61215 might be too disruptive. This turns the exception into a deprecation.
