The "Start Element Call calls" permission is no longer used and can be removed.
Can you explain why? https://github.com/matrix-org/matrix-spec-proposals/blob/matthew/group-voip/proposals/3401-group-voip.md#basic-call still seems to use m.call "Start Element Call calls"
That MSC is being superseded by MSC4143, which has no equivalent of m.call. In MatrixRTC, a call exists by virtue of there being some participants (m.rtc.member) joined to it.
@robintown okay then both options should be removed as they are MSC3401 only
Oh except https://github.com/matrix-org/matrix-spec-proposals/blob/toger5/matrixRTC/proposals/4143-matrix-rtc.md#unstable-prefix uses another MSC's unstable prefix. Is the SCT okay with this? Otherwise EW has an MSC3401 implementation seemingly by design
If we remove those permissions, what should we use to determine if the app can offer a create or a join call button? This is a problem when a room is tombstoned: https://github.com/element-hq/element-meta/issues/2808#issuecomment-2984221926.
Behind "Join element call calls" it is org.matrix.msc3401.call.member that is modified, so it is used to modify the power level to join and start a call. Is there a way to only restrict the power level to start a call then ?
