@zachleat can't say that I've ever seen that come up in glancing through the Next docs which is (IMO) a problem. If you're going to collect telemetry data on your tool it should be opt-in and very apparent upfront (that does not mean having to check the logs).
I see from the replies that Nuxt and Ember each collect data (though with different presets). Has anyone checked about Angular though? They would be the other big framework of interest.
