Ah. Yes, that’s quite a bit more specific than what I imagined from your initial description. Doesn’t that mean that you have to unhook all your references from the world at the end of the callback and find everything anew at the start of a new one? (For the most part, of course, that would mean that both the runtime and the plugin would end up using as few references as possible.) What could a runtime want to change in the meantime that pays for that suffering? I can only think of keeping callbacks active across restarts and upgrades, and even then allowing for parts to disappear seems excessive.
