Is there any merit to mapping grails version to the Java version? Like instead of Grails 7, Grails 17 (for java 17), Grails 21, Grails 25 etc, or perhaps Grails j17 etc

In Grails 4, the framework adopted semantic versioning. I don't think it is a good idea to map Grails version with Java version. Here is the blog post https://grails.org/blog/2021-01-22-grails-exciting-updates.html
