Is that why you made that absurd claim about sql injection being an explicit requirement? And that weird figure of 24 hours for handling sql injection, and api validation?

I said "db calls aren't randomly placed in try/catch - that will be absurd". Because they will be handled at app level to return uniform error messages. Now I am sure you will go on pretending that when you said "db calls aren't in try/catch", what you meant was db calls can throw an exception and app will handle it.

What did I say about None checks not necessary because of something which is visible in the code? What do you think those marshmallow schemas and use_kwargs is for?
