Recommendations To Prevent Frame Damage When Replacing Rim Strikes?

Whether the person called in to work on the door knows what they're doing is out of my hands and different groups/buildings use different service people. That might be unified 1-2 years down the road, but it's not today. We just manage the software and plan original installations; we are getting tired of the headaches introduced by people blowing out holes for the strike in the door frames or otherwise doing wonky stuff like drilling a second hole to introduce a screw at an angle to meet the bolt because they blew out the bolt hole, etc.

I'm trying to make the best of the situation, thinking of a way to make it less prone for chaos. The best I've come up with is introducing threaded rivets for the bolt holes in the frames. However, they stick over the edge of the door frames and make the strikes not flush with the frame. We could countersink, but I really do not think that is a good idea with aluminum storefront frames since there's not much to them as is. As a result, we've purchased some 1/16" strike spacer plates. However, we have to drill each of these out to accommodate the size of the head of the rivets. And I also worry that someone's just going to do a strike replacement down the road, not put the spacer plate back in, and then the strike will have play in it since it's not flush with the door frame and is sitting only on the rivets.
