This task represents the work involving with designing the experience people who have the New Discussion Tool enabled will have when they attempt to start a new discussion on a talk page, across namespaces, that has not yet been created yet.
=== Background
As discussed by @matmarex and @DannyS712 on https://gerrit.wikimedia.org/r/c/mediawiki/extensions/DiscussionTools/+/623117, adding new discussions to non-existent pages is an edge case that will need special handling.
Currently all links to such pages (red links) will append `&action=edit` which will take you straight into the full page source editor.
Junior Contributors are likely to be confused by this experience considering:
- The current experiences does not offer people guidance about what they ought to use talk pages for
- The current experience does not offer people an explicit and clear way of starting a new conversation
=== Use cases
We see there being three distinct categories of talk pages to design for:
|Namespace|Ticket
|---|---
|User talk (3)| T274831
|Your own talk page|T277329|
| All other talk (1, 5, 7, 9, 11, 13, 15, 101, 119, 711, 829)| T274832
=== Open questions
- [x] 1. Does it make most sense to consider the scope of this task as being limited to what happens when people click the `New section` / `Add topic` affordance on non-existent talk pages? //Meaning: the visual appearance of the empty page itself would be considered separately in T252902.//
-- We'll consider the experience holistically and then breakout the work needed to realize this experience after having done so. //See: T270323#6767558.//
