Hm.... just because you trust them to do certain tasks for you doesn't mean you trust them with everything?  We trust routers to forward our data and can even set the DSCP for them  (in theory - yes i know the rtcweb/DSCP story and DART)

And you can still have e.g. e2e encryption and e2e authentication on top, right?  So what is the real trust problem here?
