## Description

This reverts commit 4006b543a694f6cf77c2d8cc188c5f53f3bac1d9. As
reported in
https://github.com/bazelbuild/buildtools/pull/1386#issuecomment-3838906721
and below, this has numerous false positives and causes a lot of churn.
The checks could potentially still be useful if scoped far more tightly,
but determining this scope isn't trivial, hence a revert.
