How is a field you can introduce used to verify anything? There’s no “verification” if you choose to put whatever you want.

Or what, do you consider the field that shows up when clicking some games on steam where you just scroll the year 40 down and click whatever, age “verification”? Cuz it isn’t.

Having a date field so that parents can define their kids’ age in for non root accounts on Linux so the system, in a potential future, automatically limits access to some stuff is useful, and yet there’s no age verification being done there, besides the parents themselves knowing that what they inputted is truthful.
