Hey @SmashManiac,
So long as your apex domain is pointing at us through either an A record or CNAME/ANAME/ALIAS as above, we will perform the necessary redirect.
Validators will probably fail because, as you know, they’ll be looking for the AAAA record. This is only a necessity, as far as I’m aware, on an end-to-end IPv6 lookup (which don’t occur at the moment, again, as far as I’m aware).
This said, as per your original post, I’ve added this discussion to our open feature request!
