This issue breaks down #90292 and #82896 (comment) in the context of statement bundles.

This issue tracks the investigation of surfacing the sampling probability introduced in (#82896) to statement bundles. This is an improvement to the existing conditional statement bundling experience. Although bundles (tracing) will not always be activated, this improvement will enable users to turn on statement bundles with higher confidence that bundles will not impact all statement fingerprint executions. This will help for known outlier scenarios.

A follow up issues has been created here: #92416 to define a retention and expiration policy.
