Starting a general discussion, non-blocking:

The fact that we're plumbing experiments into telemetry smells like the feature might already be mature enough to graduate from experimental status. An experiment has a higher likelihood of being discarded than something in a more mature phase, like beta.

Discarded experiments might pollute our telemetry.

Perhaps we should start thinking of graduating prebuilds out of experimental status in the coming releases.

I don't see how one has an influence over the other. Telemetry for experimental features seems very useful to determine its usage, to potentially help with its graduation.
