An uninferred parameter stub may leak through calculation of CST(Inv<Uninferred Stub>, Nothing) into a result type. A stub type in the result type means a type error. So we can afford recalculating CST with stub-containing types filtered out, since its an error anyway. This prevents stub types leakages and helps with reporting type error diagnostics.
