Yes, expect a patch soonish.

OK. How about "We recommend to use the Travis CI infrastructure..."
instead?

Agreed. I assume your suggested wording below would be fine?

Agreed.

Agreed. I also like Stefan's suggestion to move the CI stuff
into a separate file. Any objections to this?

OK, I will remove it. My intention was to express that you need a
