Android CLI can write a tool that wraps android-cli and automatically passes the flag based on an env variable.

How would Google have enough data about a brand new product without collecting that data?

`alias android-cli='android-cli --no-metrics'`

They wouldn't. But on the other hand, they probably have a large amount of in-house Android app developers on whom they can conduct such metrics collection. I wouldn't expect outsiders to have vastly different workflows, because when you get out of the happy path with Android all you get is pain.
