The change avoids the compiler CLI internal API from mismatching the following case as lazy loading ``` import { NonLazyLoadedModule } from './non-lazy-loaded/non-lazy-loaded.module'; export function getNonLazyLoadedModule() { return NonLazyLoadedModule; } export const routes = [ { path: '/some-path', loadChildren: getNonLazyLoadedModule } ]; ``` The output of the check is later passed to `RouteDef.fromString()`, so, it makes sense to be only a string.
