At some point, yes. But I don't think that you should wait for that. If
you're interested in existing measurements, I could imagine that Dennis
would share his experiment data. And if you want to run specific
measurements, you'll have to set them up on your own anyway.

Yes, we could change the traffic model. We earlier discussed
implementing something like a ping/echo server. We could likely simulate
other applications.

It's not on the roadmap for this year, but I agree that it would be nice
to have, so maybe early 2020?
