:I agree, and hidden text in this article would be fine if it worded correctly.  The current proposed wording is too harsh, yelling in caps and looks to be a message prohibiting editing along those lines.  I suggest we find better wording per WP:HIDDEN if we indeed find consensus that a hidden note about existing consensus regarding adding an infobox.  I would suggest adding something like "Before adding an infobox to this article, please check previous discussions" and provide a handy link.  And remember, consensus can change, so maybe we need a new RFC to further explore adding an infobox to this article.
