Hmm, that's interesting, deleting with ID not found was my whole point of
using "result" instead of "reason". What version of ES are you using to test
against? I wonder if the behavior has changed at some point to have errors =
false when it was true during my testing? Also now I'm rethinking whether we
should treat "not-found deletes" as errors since ES doesn't seem to.---
