It sets the limits on what people can expect from GENERIC in this context. We may remove support for 4.x binaries from GENERIC at some later time, we may keep it. Either way, it doesn't affect upgrading. Part of the minimum upgrading guarantee is that we have old binary support in GENERIC for all branches we support upgrading from. We can (and do) support additional binaries, and having the clarification here doesn't change that. Warner
