💭 thought: ‏almost all usages of addTelemetryUsage is only providing a feature name. It could be shorter to change the signature to something like:

addTelemetryUsage("feature", { optional_context: true })

when introducing the API, I spent some time trying something like this but did not managed to have the typings working.
Don't hesitate to have a shot at it, happy to tweak that in a following PR.
