@turt2live How do we want to move forward here?

If you agree with the proposal, I can prepare the required PRs in the other repositories.

@dhenneke the next steps for this MSC would be getting review from the community and Spec Core Team (SCT, which includes myself). Once that review has been done then we'll take a look at getting the changes incorporated into the spec, though for widgets this is typically pretty slow due to the shear size of the feature (unfortunately). The place to seek that review is #matrix-spec:matrix.org on Matrix.

If you're more concerned with the capability being added to the widget-api and react-sdk projects respectively, there's some potential changes to which team is responsible for maintaining widgets coming up. I'll have more information in the next few weeks (hopefully) - ping me in #matrix-widgets:matrix.org after July 13th or so and we can go from there. (or, if there's something more urgent than that needed, let me know and we'll figure it out).

I cleaned up our prototype implementation and created the respective draft pull requests.

We would really like to see this going forward, meaning getting into the widget-api and react-sdk so we can work with it in our widgets.

Is there any desire to require widgets to request the user's permission per room type that they'd like to create? For instance, I'd possibly be happy with a widget creating lots of m.calendar.event type rooms, but less happy for it to have the ability to create Spaces.

[dhenneke]

Yes, that could be reasonable. There could be a m.create_room (or m.create_room:?) capability to add a room without a type, and m.create_room:<room-type> for specific types. I'm not sure if there would be a use case for a m.create_room:* capability. Say someone builds a generic room manager widget for some reason, it could also make use of MSC2974 to request that on demand.
