[snip impressive debugging story]

As much as I would on principle rather not stick to a legacy, TCP-only

I can say that right now, my home internet, blocking UDP 443, and
making tons of insecure DNS queries -- is the most stable, fastest,
most usable and enjoyable home internet I've ever had. And my users
agree -- they no longer turn off wifi.

Rather than hobble your home network to work around a misbehaving ISP, have you considered simply getting a new ISP?
