We didn't use the word "comprehensive", "complete", or "thorough", and obviously we didn't include every password manager in our evaluation, so I'm not sure what reason you have to believe that we were aiming to be "comprehensive."
We were aiming to evaluate the features / issues we care about against the password managers we were most likely to want to use. We published the results of our evaluation because we thought it might be useful to some people, not because we thought or intended for it to be all things to all people.
We didn't include security audits in our evaluation because, we are skeptical of their value and do not consider them a significant differentiator.
For example, in our experience trying to keep our own application secure, our HackerOne bug-bounty program has identified far more issues than the white-box security audits we've commissioned, at far lower cost.
