Screw to wood connections require attention. Especially on newish wood. Roger recommends hand tightening neck pocket bolts and strap lock screws at every intonation and string change.
This isn’t screw to wood - the pickup height adjustment screws have metal threaded inserts and there’s enough tolerance there to allow them to loosen pretty easily.
While I do make sure strap button screws are tight before every gig and occasionally make sure my neck screws are snug, I’ve never had an issue with pickup height adjustment screws loosen on their own when screwed directly into wood.

Yes - I mentioned this in my original post. Clear nail polish works great too if you’re in a pinch.
Still not ideal, IMO. Threaded inserts seem a bit unnecessary when it comes to locations that don’t require a lot of tightening, retightening, removing, etc.
