Description

In last beam release, Read.Bounded and Read.Unbounded are deprecated and beam tends to move to Impulse usage.

This is a huge breaking change since users can't rely on custom pre-runner pipeline visitor to instrument their pipelines anymore or even identify the transform accurately anymore.

This issue is about ensure that SDF or not Read.Bounded and Read.Unbounded is a stable transform matcher and can still be used by user code to identify inputs.
