Eris' and Orcus' slow rotations?[edit]

136199 Eris has since been shown to be mutually tidally locked to its large moon Dysnomia^[1], and thus is now known to have a rotation period of 378.86 hours (15.786 days), which would put it between 10331 Peterbluhm and (252079) 2000 SY₃₀₆.

On top of that, it is not confirmed, but very much plausible, that another dwarf planet, 90842 Orcus, is also mutually tidally locked to its large moon Vanth^[2]. If so, that would put its rotational period at 228.94 hours (9.539 days), which would put it between (95355) 2002 CQ₁₄₁ and (131381) 2001 KU₃₉.

Eris' slow rotation is confirmed, whereas Orcus' is not, so should Eris' confirmed slow rotation be added to the list? What about Orcus'?
