Flexible would be offering some kind of "anytype" column or similar. I'd still be wary of it, but there you could properly claim that one does not have to use it, and it would mean correctness is still enforced on all other columns. This doesn't bother you because you have your own schema layer. Imagine your ORM would stop enforcing types, and return a number when a string property was requested.
