DITA 2.0 proposals

Hi,

1. Is the TC still open to new DITA 2.0 proposals?

If so ...

2. The 'Drafts' folder contains DITA 2.0 Proposal template HTML - early draft, and DITA 2.0 Proposal template - early draft. Are these the latest templates, and most current? Or are there finalised templates elsewhere?

3. Is GitHub just used for content models only, or do the proposals end up there, at some stage? The proposals mention issue numbers, which I assume is a GitHub reference.

Many thanks,

David
