Lists, extensible protobufs, etc are indeed great in their extensibility. The issue I would see (if I worked at Cloudflare) isn’t to using a list — it’s that the list is the same list that’s used for externally visible HTTP headers.

I don't see that as a problem at all:

"Hey any teams out there, before you can add internal headers, you need to register them with some service." Then the list is loaded from static storage at startup time and/or refreshed on some periodic basis.
