Self-tapping screws and device integrity/sturdiness

How much of an issue are the self-tapping screws (if that is what they are?) of the shell of the Steam Deck for repairs? If you're careful by screwing the screw counter-clockwise first, to hit the existing thread - will the existing thread still be slightly worn when fastening the case?

This Reddit thread is perhaps relevant: https://www.reddit.com/r/SteamDeck/comme...

What's the best way to proceed? The Reddit thread suggests using a Dremel to file away the cutting part of the thread.

What have other people done?
