One Problem in General I see with Telemetry is that I would treat it like Analytic Cookies get treated under the

DSGVO

(The German law for Data Protection) in which Every Cookie That is not relevant to the Website you are using, needs to be

Opt In

and you could even get in trouble if you hide it behind a button like

Accept all Cookies

and make it harder to only accept the needed Cookies. There are some funny but understandable rules, around such things sadly telemetry has not yet such rules or Win doof wouldn't be calling home so much.
