chore: add additional document statuses

[toddbaert]

Adds document statuses explaining stability of various spec documents and sub-sections.

This is important as we move toward's 1.0 SDK releases and a stable spec.

I'm not sure the benefit of Mixed, but it's not like it's a problem

Ya I was hesitant about Mixed. It's not really a meaningful status unto itself, but more of a meta-status. I feel confident about the rest.

TBH we can probably completely remove it. We can annotate sections with statuses, it just means you'll have navigate to them to see them.

Is there going to be requirements or guidelines on how the promotion is determined? For example what is required to go from Experimental -> Hardening?

@InTheCloudDan that's a good question. I think some kind of formality could be good. I'm not sure what that could be. I'll think about it :thinking:

Anyone else have ideas for this?

• added simple summary statements
• added recommendations about prod usage
• added statement describing that the TSC approves graduation:

It is the responsibility of the Technical Steering Committee to consider and approve the graduation of documents.
