A maintainer of a layer should make a deliberate decision of adding a release or dropping one from the compatibility list. It should be an attestation that the layer's compatibility with the releases in the list is actually maintained and tested. There have been changes to the syntax to conditional variables. Your layer might well be compatible with all of the releases and it's great if you tested it.
