These things exist to eliminate the risk of ever serving stale information from a materialised view. I.e., their benefit is political/reputational as much as they are technical in the sense that they save you effort like remembering to invalidate a MV after an ingest operation.

Stale MV is a thing you only ever burn your fingers on once. Like how "It's not DNS" is a common meme in networking.
