HTTPS RR is great, but not super useful at this point... I wish they would would invest more in stuff that would have a practical benefit to user experience/security. Firefox's lack of TouchID support for WebAuthn is what keeps me on Chrome.
I still find it a shame that SRV records never caught on. Active Directory uses them very well
- Apple devices running iOS 14+ are querying HTTPS RR for some time now, and they work on normal DNS setups.
- Google Chrome just enabled HTTPS RR queries over standard DNS on version 92.
