Please add more context here in this issue's description to summarize the problem and what you think we should do.

With a description about what's in the codebase now and what the proposed change, if any, should be and what the pro's con's are will help us continue discussion.

We should do validations only in development mode. Closing since the original validation is also no longer needed.
