Are the currently deployed and used versions of the go compiler going to suddenly start sending telemetry? Or is it just a future version that someone would have to deliberately upgrade to?

Personally, when a new version of golang comes out, I like to read the release notes and then adjust my build environments with the necessary environment changes for the new features.
