> We can't just send deprecation notices to random contact emails (if there's any) on websites. We can't just open a "support request" to L1 customer support of websites telling them their site might not work soon.

What about folks who've registered for either origin trials or Google Search Console? Or Google Analytics?

That said, I'd love it if telemetry APIs were baked into the web, perhaps OpenTelemetry API support? Then website owners could set up their own error reporting OTLP endpoints or services to receive sampled deprecation alerts in a standard way, rather than assuming everybody can read the developer console in an end-user's browser (especially when it's hidden most of the time...)

Bonus points if we can ignore errors caused by extensions, or have extra feedback as to which extensions might be causing problems. Double bonus points if there's a UI so end users can choose whether to share this data or not, or to cache and sync the data so it only gets shared when on wifi or idle, in an extremely compressed way, and to provide a settings screen where you can browse what telemetry or errors are shared from/to websites in your history.
