Telemetry enableTelemetry setting: does it fully disable data collection in all VSCodium channels?

Telemetry enableTelemetry setting

VSCodium is marketed as a “no telemetry” edition of VS Code, yet the upstream settings schema still exposes telemetry.enableTelemetry. The goal is to determine whether setting telemetry.enableTelemetry to false truly suppresses all telemetry traffic across every VSCodium distribution (stable, insiders, nightly). The main uncertainty lies in whether the setting blocks every telemetry endpoint or whether certain background services bypass it, especially in newer releases where VS Code upstream may have added new telemetry hooks.

Because the documentation does not explicitly confirm complete telemetry elimination, runtime verification is required. This raises the following specific questions:

• Does telemetry.enableTelemetry = false prevent all outbound telemetry requests in VSCodium Insiders 1.84 and later?
• Are there any hidden telemetry endpoints that ignore this setting, perhaps in extensions or background tasks?
• What differences, if any, exist between stable and insiders channels regarding telemetry suppression?
