To protect myself or my company, what about a pihole (or similar) that rejects any TLS connection attempted with certs signed by these root CA?

That's illegal then. But the pihole won't do the trick, you need to remove the mandated certs from your browsers certstore. If these certs are used for legitimate places (e.g. EU or state websites, and I'll bet they will) you then will get a certificate error.

Of course there is still HSTS, but that's not supported by all tech using TLS.

Prediction: If this passes, users having to bypass cert errors will be the new cookie popup.

TLS 1.3 encrypts server certificate, so it will not be possible to filter such connections out using just passive inspection.

Instead of a pihole, you'd run a https proxy that doesn't trust the certs i guess.
