I am not inclined to merge this change as I think it does not provide any benefit over the current status. We are consciously checking every supported version explicitly. Linting is a part of this check.
Furthermore since we support Elixir 1.15+ we do want to check Elixir 1.15.0 as it is the minimum supported version. Your proposal would start checking on 1.15.8 as it is the latest version on that branch. This means that there would be previous versions that are supported but not checked in the CI.
