Correct, SIGDocs is currently holding a discussion at Documentation leadership responsibilities and I believe that some other teams (Core) are planning to closely watch it for their own leadership.
You are welcome to participate!
The core idea, from SIG Specific Team Leads, is to avoid a bottleneck with permissions.
We will be electing 2 leads for SIGDocs at SIG Documentation: Team Leadership Election when that discussion has happened. Until that happens, myself and @coded are acting leaders.
