Comment (by strk):

 Given the side-effect of turning an inequality operator against
 TopoGeometry ambiguous (see #5546) I'd like to understand what exactly
 made those operators ambiguous for the core geometry type. I guess
 ambiguity derives from the presence of implicit casts from the type to
 some other type. What explicit casts does geometry have ? Did that change
 any recently ?
