> Since alias records (a.k.a CNAME records) aren't permitted at the apex... Technically this is a subset of the rule that CNAME ("canonical") records cannot co-exist with any other record type with the same label. e.g. it's illegal to have `foo.example.com` be both a CNAME and an A record. Since an SOA record is required at the zone apex, you can't also have a CNAME record there. :-(
