Yep. There was talk of ANAME records at IETF but that doesn't seem to be really going somewhere Some DNS servers implement something they often call ALIAS, but it's basically the equivalent of having a crontab mirror the settings of the records you're referring to, and breaks eg. geo-dependent address resolving (so not that useful for referring to a CDN, which is why you'd most likely want this)
