Fully agree. I can't speak for Pete, but I am not willing to re-open the document to add characters to a list of optional characters. In fact, I'm not even sure there will be a "we" around in six months: the WG should close down after we have fulfilled our charter.

And here we fully disagree. I think defining the rules for registries for any of the optional parts of the document will take at least another year, and we have already hit the exhaustion point. I see absolutely no upside for a registry of optional suggestions for an Informational RFC, with a significant downside of taking a lot of review time that could be better spent elsewhere.

I see no "need" to reopen the document, ever. If someone wants to prepare a document with a different view, or with the same view but additional characters, that's fine, and quite easy in the RFC process.

We certainly agree on the likelihood of desired additions, but I think not on the "need" for a revision to the WG's document.
