Pitches for changes to site, not Swift language: Where do they go?

I’d like to pitch the creation of a new Category under the Using Swift Category, but I’m not sure where the pitch goes. Do I post here in Site Feedback? The recent pitch about adding Community Showcase was done in Evolution/Announcements, which is admin-only, so I can’t pitch there.

Where is the right place to pitch this?

Yes, start a thread in Site Feedback.
