Add riotchat to rootUrlApps

[gary-kim]

@Sorunome is working on a Matrix integration for Nextcloud but it requires root url routes for some of the Matrix routes so this PR adds riotchat to the allowed root url apps.

gary-kim/riotchat#369

Not a huge fan but 🤷

Can you maybe elaborate a bit further why those are needed in the root and why having them under the app url-subspace doesn't work for that use case?

[Sorunome]

Sure!

The idea was to easily share media (images etc.) from nextcloud into matrix. (Matrix is a federated chat protocol.) For that, nextcloud could act as a matrix media repository. The matrix protocol, however, requires those endpoints to start with /_matrix/media, sub-paths are unfortunately not possible. Thus, root URLs are required so that nextcloud can act as a matrix media repository. Other, non-matrix-protocol-related endpoints ofc still use the app namespace.

Is there any chance Matrix can add support for .well-known URLs for discovery? I can see the use-case here, but this seems a tad hacky :)

Matrix already has .well-known for discovering server domains, but not for paths. There is a semi-related issue open to this already, about pushers (push notification targets). There does not seem to be an issue to add such configurability to all endpoints, and thus the path forward for that would be very slow etc., having to go through an MSC (Matrix Spec Change) process, etc.

then I think this is an issue with matrix. Implementing workarounds here does not seems to be the right solution imho. I'm in favour of closing :)

Pushed over for two years. I'm assuming we can at least unassign from the milestone. @gary-kim is this change still required?

[Thatoo]

We'd really like to be able to share media (files, images etc.) from nextcloud into matrix.
I read the thread and didn't understand the reason it has been rejected till now.
I only read a mention of not "liking the idea" but no real argument. Why? For what reason? Security?

Yes, this issue is still needed unless a Matrix MSC is established : matrix-org/matrix-spec#693

Can't riotchat be added to rootUrlApps along spreed? At least untill Matrix handle the .well-known solution to manage subpath of /_matrix/ ?
