Is this printing always desirable in the IR? While focusing on this one attribute seems better, the overall IR flow can become unbearable.

This is more of an enabler than a prescriptive change and it does not affect any existing IR formatting.
It is mainly intended to expose formatting capabilities to custom attribute printers. That greatly improves readability in specific cases where attributes carry sizable structured information. Much of the boilerplate can be avoided with custom printers. It has proven effective in a large codebase of ours.
