The problem with this mechanism is that reviewers have no liability, because their comment is anonymous to the author and won't be available to the readers, as it won't be published as part of the article. The result is that reviewers are not made accountable now or in the future for inaccuracies in their review, blatant attacks, or tactical requests for additional irrelevant investigation just out of spite or to stall you so that they can scoop your paper.
Occasionally, the Editor can step in and disregard a particularly obnoxious reviewer, but it depends on the editor, the journal, and the political/scientific strength of the reviewer.
