Do Credit Bureaus require reporting of both positive (on-time payments) and negative (late payments)?

Reporting late payments is a common practice because it provides an accurate picture of a borrower's credit history and payment behavior, which is essential for assessing creditworthiness. If there are gaps in an individuals credit history (due to not reporting a negative month), a Credit Bureau may dismiss this tradeline's data as it would be inconsistent and therefore unreliable.
