Backport 1/1 commits from #155721 on behalf of @yuzefovich.
We just made a change to include skipped FKs (those that we deemed "irrelevant") in the commented out form. This commit improves that logic by adding a comment for why these FKs are commented out, to reduce possible confusion.
Epic: None
Release note: None
Release justification: low-risk supportability improvement.
