Just for show
Since Chad Wolf isn't legally in that office, the court already blocks Chad Wolf's rule changes, so he can do any number of electioneering rule changes that won't actually come into force.
Chad Wolf's latest rule change, will be blocked immediately, just like the last rule change. But that's not necessarily a bad thing for Chad. He's a lobbyist. Do you attack your corporate sponsors just before an election? No, but you can pretend to for party votes! After the election he can drop the rule changes which were blocked anyway.
He should not be receiving salary, and salary he did receive should be reclaimed, checks cannot be legally authorized by him, spending cannot be legally approved by him. Did you get paid, due to approval from Chad? Bad news...
If you give him access to security details that only his position allows for, then you've committed a crime, because he's not legally in that position. Day to day decision making has no authority. You do not have the legal cover of "I was following orders" when the court says his orders are illegitimate. I'm surprised IT is allowed to allocate him an email address or account on the server too.
Most importantly, he cannot order a "challenge voters at polling stations" order, the way he sent troops into Portland.
So he's not usable as a Trump militia to challenge voters at the polls. (+Proud Boys march was a disaster, tiny numbers of people showed up, outnumbered by journalist, not enough to intimidate people beyond a few polling stations).
US might be a shit show right now, but the shovels are out.
