KMS keys try to be smart about not generating impossible dependencies between multiple stacks, which CodePipeline takes advantage of for its support stacks. However, because the logic that tests for this case has an `instanceof Construct` in its code path, if there are ever multiple copies of the `constructs` library in the NPM tree the test will fail, and the resulting error will be very confusing. This situation can arise when people flip back and forth between CDK v1 and v2, because `package-lock.json` will contain half-baked dependency trees; people will be looking at their code but the issue will be in invisible state. Be more liberal in detecting that a construct is, in fact, a construct to get around this.

| * multiple copies of the `constructs` library on disk. This can happen | ||

| * Pipelines is going to an error that says "Can't use Pipeline/Pipeline/Role in | ||

This is how production software looks like!

Should we move this to the constructs library? Feels like it might be a better place to put this code, no?

For sure. Don't forget to add it to both versions :)
