Uploading the cross-signing keys causes a discontinuity in the stream_id sequence, so next time there is a device update, all the servers that you share a room with will need to do a complete resync of your device list.

I think the issue is that the x-signing-key upload bumps the stream id, but doesn't cause a device update edu.

this isn't going to be great for performance.
