Partially degenerate?
editI don't see how coincident vertices is a problem – is this not already true for the regular compound of ten tetrahedra and regular compound of five cubes, for example? And I don't think anyone calls these compounds partially degenerate.
OTOH, Norman Johnson rejects this as a proper polyhedron, along with the duals of the hemipolyhedra and the small hexagrammic hexecontahedron, probably because of the problem of coincident/fissary (fissary = compound vertex figure) vertices. (Whether they're coincident or fissary depends on whether you look at the coincident vertices as two vertices with triangular vertfigs superimposed, or one vertex with a hexagrammic vertfig; but is the latter really the dual of seside?)
