Thanks for the review, @joker-eph! I have reverted the false positives and only left the relevant fixes in this PR. Also updated the PR description, so that it is up-to-date with the PR content. Please take another look.

Regarding the checker, I'll look into reducing the false positives, such as only detecting uses that actually dereference an operation.
