There are no small amount of times when you'd want to wrap a block with links, including headers, summaries, and composites. It's actually unfortunate that in so many cases where people wrap blocks with anchors, they go for the inner-wrap method which has a major downside in that the inner anchor does not span the entire block by default. That means that there are a lot of, say, logos that have padding you can't click on (contrast with the horrible ads that have clickable whitespace).
