I ❤️ the newly introduced baseline feature!

However, when you have a rather complex phpstan.neon configuration file, it's a bit difficult to generate a baseline.

That is, currently I need to duplicate the phpstan.neon that is used for running phpstan, with the only difference that the duplicated version of phpstan.neon - used for generating the baseline - does not not include the generated baseline.

Perhaps it could be made a bit easier if the baseline could be specified via a parameter?

I imagine that that parameter could then just be ignored when generating the baseline, perhaps even using a dedicated command?

This way it would not be necessary to duplicate the configuration.
