parentSend device list updates to application services (MSC3202) - part 1 (#11881) (diff)
downloadsynapse-c31c1091d4b591af0683e14363c5bf430b2f045e.tar.xz
Remove the unused and unstable `/aggregations` endpoint. (#12293)
This endpoint was removed from MSC2675 before it was approved.
It is currently unspecified (even in any MSCs) and therefore subject to
removal. It is not implemented by any known clients.

This also changes the bundled aggregation format for `m.annotation`,
which previously included pagination tokens for the `/aggregations`
endpoint, which are no longer useful.
