Firefox and Chrome have HTTPS/SVCB support enabled since two to four 
major release and since years on ios.
CNAME at the apes is only for browser/marketing purpose and could start 
to go away now.
Serious tools/softwares will be updated for ech/TLSv1.3 support.
All the others could simply live without HTTPS/SVCB an without CNAME at 
the apex.
