AFAIK, glance image cache is transparent to the user: so the user don't know if he is using cache or not. It also doesn't have any dependencies on nova caching implementation. AFAIU caching in nova is managed by Nova so please change affected projects. Please, reopen a bug if there is glance dependencies on it.
