Very basic question... Looking at the External Config plugin, it says in the release notes "Notice, that from Grails 7, this plugin is released at a part of Grails core!". Does that mean I don't need to use

implementation 'dk.glasius:external-config:4.0.1'

and can just use the grails.config.locations as if it is part of Grails (which it presumably is as of 7)?

Yes, it's been integrated into grails-core in 7. You can simply remove that dependency and it's included via the config dependency which is part of

grails-core

👍

Given the desire to run grails in a container, one of the common use cases for containers is to have "production" specific configuration that's only present on a production configuration / container. that will differ from a dev / test environment. The support for an optional configuration at a different location is why we brought it into grails-core. Special thanks to @sbglasius for his support there.
