The conformance tests for this repo are configured to use buildpacks, so they're using the version of this framework that is already released and supported in the buildpack rather than what's in the current source tree.

Instead, the conformance tests should be run locally against the current source tree. For example, this is what the .NET framework does.

This will ensure that we are aware if a given PR breaks the conformance tests, as the status will match the current state of the repo.
