Implementation requirements:

  • None, in my opinion. See "unstable prefix" section for rationale.

Team member @clokep has proposed to merge this. The next step is review by the rest of the tagged people:

Once at least 75% of reviewers approve (and there are no outstanding concerns), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

The following methods are *not* included because they don't have foreseeable use in Matrix:

* `CONNECT`
* `TRACE`

I might suggest that this could be an MSC where we propose a literal update to the text of the spec: the current spec just plucks a recommendation out of thin air with no explanation of why it's recommended, but this MSC contains a bunch of useful context. I know you're trying to write it without including a reference to an in-review MSC in the spec, but I'm finding the result quite obtuse: "future use" just makes me wonder why the server wouldn't add those methods when it has an endpoint that actually uses them.

I would suggest something along the lines of, "if you implement all of the Matrix spec, you'll need this set, however this expanded set would be safe and sensible should you ever implement any MSCs that use them"?

or maybe something along the lines of "... if you implement any other endpoints that use other HTTP methods, make sure that you also include those methods on CORS".

#4138 (comment) is in line with this thread.

Will update the MSC.

it feels weird to be allowing methods without matching MSCs that demand them, but not enough to block it.

The [`Access-Control-Allow-Methods` header's recommended value](https://spec.matrix.org/v1.10/client-server-api/#web-browser-clients)
is updated to include the following:

* `PATCH` - A plausibly useful HTTP method for future use.
