I get the impression this directive is more about sending a message.

Edit: I learned something new.

A pardon doesn't remove a conviction and discriminating against someone convicted of a crime isn't federally illegal, as that isn't a protected class. I'm not sure how this works with Illinois law given we have Conviction Record Protection. I do know state law specifically forbids hiring people with specific convictions (particularly violent ones) for certain jobs -- e.g. Police, fire, etc. And IDPH will absolutely pull your licenses for something as "minor" as not paying child support.
