Well, no. Because JSON & by extension OpenAPI lack a Date type you can't easily add validations about dates to those schemas. Like you can't say this particular date must be in the past in an OpenAPI spec because it has no concept of a date. The best you can do is a regex on the strings you call dates but that falls apart pretty quick.

I don't get these types of arguments.

There's zero reason you can't write code that parses a date in an expected format (and throws an error if the date is formatted incorrectly) and then checks that the date is in the past.

Yes, it does mean you'll spend time writing more code (You know, the job you're being paid to do?), and it would be nice if your data format supported such automatic checking functionality out of the box, but to say "It can't be done!" is just plain silly.

It's a good thing I didn't say that.

The whole point of WSDLs and OpenAPI is to minimize the amount of time it takes to consume your API. Saying you have to write more code is highlighting the shortcomings of OpenAPI at doing the only thing it's built to do. Which is why companies have largely punted on providing OpenAPI specs in favor of maintaining libraries in a handful of popular languages.
