Follow-up to #2408371: Proxies of module interfaces don't work
- Currently middlewares after page_cache are not proxied as the ProxyServicesPass() comes too early to find the dynamic 'lazy' definition.
Why this should be an RC target
Due to changes of the proxy services, we no longer have lazy middlewares which causes a bit of an overhead for page cache. This is a performance only change,
but could totally be changed afterwards
