Please excuse my lack of knowledge about the opcache internals, but can't this be remedied by some kind of namespacing? I don't know how the lookup rules are, but I assume it's by file path - so if you're preloading and serving preloading bundles, shouldn't this (at least as a PoC) work with a random prefix, or even the app entry point? This whole thing is basically tailored to people running their own applications on their own stack - but if this restriction was lifted this could be handy for shared hosting or even for people with multiple application (stacks) on the same webserver. Yes, I'm sure it's not that simple, but I don't really grasp why this is different than the current opcache lookup rules. Greetings, Florian
