This is excellent news for human persons. Protocol implementations that only allow TLS are not very robust without human maintenence for more than a few years. That said, the human person use cases for HTTP/2 are pretty limited. Generally HTTP/1.1 is a better choice.

I'd much rather http2/3 with an expired cert over cleartext anyday.
