@busy-ability-54059, @bumpy-lighter-59125 had a question about whether a UI Extension can send telemetry or anonymized usage info to arbitrary endpoints. Is there anything in the extensions framework or the Rancher UI which would prevent this?

From the top of my head, the only problem I would see there would be them hitting CORS (Cross-Origin Resource Sharing) issues because they are attempting to communicate to another domain. Someone inquired me about an extension that used Sentry https://sentry.io/welcome/ ,during a hackweek project, and I think they were successful in getting data back to the Sentry servers

same thoughts here as well
