Review Comment:
Consider validating the string property. Right now, if someone were to typo
as e.g. `properties["CloudFetch"] = "flase";` the property value would be
silently ignored. (Similarly, `properties["CloudFetc"] = "false";` would be
ignored but I'm not sure how consistently drivers are producing errors for
unsupported properties.)
