I'd be happy if DNS and NTP would just get off their butts and switch to TCP. No, DoH doesn't count.

  Why would NTP be better with retransmisson of stale packets and go-back-N semantics on drops?

    UDP can be spoofed for amplification attacks, and since ISPs won't implement reverse path filtering, the only other option is to get rid of UDP.

  Normal DNS will switch to TCP for any large request and has done for quite some time.

    Unless you're using the musl libc - which is in heavy use in conteainerized applications

      OK well if it does zone transfers those are over TCP only and always have been.

        There is more to DNS than just zone transfers...
