I disagree, with a caveat. Assuming your review tool supports "Resolved" or "No Action Required" comments (ours does), it's rather easy to distinguish something that is informative from something that is actionable. I am now recalling that some review tools don't distinguish open/unresolved comments from resolved or informative comments, which would make this more of a trade-off than an obvious win.
