I use it from time to time yeah. The problem is, I don't know how to properly filter the output (I don't think what you are suggesting is possible) so it's annoying to read.

In this case, I actually ran it before submitting the PR, but only looked at mkt.ratings.views coverage (97%, 3 uncovered lines, one is a FIXME, one is a false positive, the other I don't know) and not mkt.api.authorization.
