I agree. It's better to keep ''bifurcator'' as requiring immediate
proximity of occupied square as obstacle.  Gryphon is not what we usually
mean and does not really qualify except extremely inclusively for having
two ways from the first step, like 20th-century Cavalier and Duke of
Renaissance Chess.  Neither are all of Winther's ''pure bifurcators''
more restrictively since many can move or capture without bifurcation.
Likewise Grasshopper has genuine similarity to Crossrook but it has in no
way either Crossrook's divergence or bifurcation. Bifurcating should not
mean also interaction only with the edge for splitting into two routes; see bifurcation article exceptions. There is also splitting from one to three, and that would not be
''bi''-furcating. If the occupied square triggering is distant not proximate, that is coordination, not bifurcation or not trifurcation. Which are the natural, or more correct, bifurcators?
The one(s) that bounce(s), that jump(s), or that collide(s)? That is one of the
purposes for outsiders than Winther.  Go to something like Provocatur or Venator for the article on Bifurcation defining:
