It can slow down DX since these are ran whether you're currently running a performance trace or not. It can also show up as misleading since these add time to the "Remaining Effects" entry. I'm not adding all props to the entries. Instead, I'm only adding the changed props after diffing and none for initial mount. I'm trying to as much as possible pick a fast path when possible. I'm also only logging this for the "render" entries and not the effects. If we did something for effects, it would be more like checking with dep changed. This could still have a negative effect on dev performance since we're now also using the slower `performance.measure` API when there's a diff.
