The fragility of shellability in this respect can be seen as a good thing: there are lots of tools to compute homotopy type of a complex, but shellability (when carefully examined) tells you a fair bit about the "homeomorphism type" of the complex.
WebSHELLABLE COMPLEXES AND TOPOLOGY OF DIAGONAL ARRANGEMENTS SANGWOOK KIM Abstract. We prove that if a simplicial complex ∆ is shellable, then the intersection lattice L∆ for the corresponding diagonal arrangement A∆ is homotopy equivalent to a wedge of spheres. Furthermore, we describe pre-cisely the spheres in the wedge, based … Webshellable, where v is a vertex not in K (see Section 2). Thus, the hardness of deciding shellability easily propagates to higher-dimensional complexes, even to cones. Corollary …
