I do think you are entitled to filter for a specific age group implicitly, but it doesn't make it any less discriminatory.

Example: statistically the odds of someone graduating from college being over 30 are low. Therefore if I claim that I hire college graduates I get to also filter implicitly by age.

Then the question is: assuming an inherent bias of sample, is it desirable or undesirable to introduce a "function" that attempts some mitigation? I see the "functions" that attempt to mitigate sexism, racism but not ageism.

It feels like companies or organizations are just fine with slapping a paragraph at the end of an announcement that parrots "we are inclusive trust us" without any real adjustment and call it a day.
