If you're expecting an answer different than "yes" to either of these questions, it means you've made a very expensive mistake much earlier in the process.

The right time to ask if anyone will be using a specific portion of the app is when the feature is being proposed, not after it's been implemented and released. Replacing discovery up front with post-release telemetry is a sure way to lose money.

Conversely, if you're not making that mistake, then you don't really need telemetry to tell you what you already know.
