nsupdate DoH/DoT support
nsupdate didn't come up in the DoH/DoT high level design doc so at Ondřej's suggestion this is a feature request to hopefully get it on the radar.
I'm not aware of any significant deployments of DNS UPDATE and DoH/DoT beyond Apple's now defunct use of DoT in Back to My Mac but I expect that'll change as we see DoH/DoT adopted more generally.
Personally I'm not that interested in DoH but DoT is definitely something I'd like to see supported as I'm using it with SIG(0) signed updates in my own (experimental) software.
If you're reading this and would like to see DoH or DoT make it in to nsupdate, please comment or hit the thumbs-up button.
