The other big advantage of the HTTPS record is that it allows for proper CNAME-like delegation at the domain apex, rather than requiring CNAME flattening hacks that can cause routing issues on CDNs which use GeoDNS in addition to or instead of anycast. If you've ever seen a platform recommend using a www subdomain instead of an apex domain, that's why, and it's part of why Akamai pushed for HTTPS records to be standardized since they use GeoDNS.
