Just don't, I want simple text fields where I can type without being attacked by a script. I want my autofill to work properly, I want to be able to copy paste without any strange behaviour. I want to type the delimiter. And you should be locale aware, for 2019-02-24 I would type 24.2.19. Of course you might target only the US market with your form, but the problem is that bad practices are spreading to global developers.
