These were overlooked because they live on a docs branches in the old location. Most have not been updated in many years.

Some of this documentation already exists in https://docs.grails.org/snapshot/guide/single.html#profiles

The goal is to incorporate the parts that are missing into the Application Profiles section of the main documentation.
