Core Platform Team/Initiative/EditPage/Initiative Vision

Vision: MediaWiki has an edit controller that can be used with different edit views for different content models. MediaWiki supports editing of non-textual content models defined by extensions.
Stakeholder(s): MediaWiki developers (core and extensions) will benefit from clearer, more testable code Quality + test engineering may be interested since we are making code more testable by removing coupling. The editing team should be consulted to see if they have wishes for the new system that go beyond re-implementing current behavior in a MVC way.	Problem: EditPage is a huge class with unclear information flow that bundles controller logic with view code. EditPage is not testable in a straight forward and consistent way. APIs currently simulate web requests in order to re-use the controller part of EditPage.		Solution: Refactor EditPage to allow different frontends (view) for different kinds of context. Extract the controller part of EditPage so it can be re-used easily by API modules/endpoints.	Aligned Goals: Improve code quality by reducing coupling Improve code health by improving testability Improve maintainability by modeling domain concepts clearly	Success Metrics:
