You mean, like https://pad.kernel.org ? :)

However, a large part of why I was suggesting a git repo is because it is
automatically redistributable, clonable, and verifiable using builtin git
tools. We have end-to-end attestation with git, but we don't have it with
etherpad or a wiki. If the goal is to use a document that solicits acks and
other input across subsystems, then having a tamper-evident backend may be
important.
