The HTTPS RR Type was specifically added to address the apex RR issue. In
fact, when the whole SVCB idea first came up, there was one annoying DNSOP
co-chair who was adamant that their solutions address the apex case, as it
was the biggest non-standard thing.  It's not a 100% replacement, but it is
fairly close.

I include an image of a slide which was presented by the SVCB authors on
the pros/cons between SVCB and ANAME (aka ALIAS) from an IETF long since
past.
