You are confused.

A) I was arguing in favor of the current documentation, written by
    Nick Coghlan. You were arguing in favor of Yuval's thing. You appear
    to have forgotten this, and are now agreeing with me.
B) Obviously there is no empirical evidence for anything, because
    Yuval's thing is unpublished, and the current documentation was added
    two days ago to the dev branch of the docs.
