A "TotallyDisputed" notice would probably be appropriate, given the depth of disagreement that exists here, but I cannot understand why highlighting statements identified by some as "dubious" would constitute "disfiguring the article".  SlimVirgin has also used that wording recently, but I rather think that inaccurate and irrelevant information is more of a "disfigurement" than is a template notice.

To answer your second question: my "side" has brought forward a proposal, and the other side has not yet responded.  This is sadly consistent with recent patterns of delay.  (I'll make no comment on whether or not this is a deliberate strategy.)
