It is accurate to delete features that no longer exist. Your change-set comment is informative: thank you for submitting one. It's also good that you included a source. Just know that local knowlege can refer to things like 'my friend told me that a resturaunt I know of shut down', If you have actually seen for yourself that the buisness is no longer opperational, then you can state your source as "survey" instead which carries more credence.
