- we used to to this by deleting operator delete, but this prevented the internal "F" classes from being virtual; which can be useful when using EntityManger::Listener. now we just make the destructor protected in each class. - EntityManger::Listener now has a virtual destructor so that objects could be correctly destroyed from Listener*
- all component managers now have the same "base" API
- getComponentCount()
- empty()
- getEntity()
- getEntities()
- Scene now has getEntityCount()
- EntityManager now has getEntityCount()
- all component manager implement gc() the same way, by calling destroy()
- SingleInstanceComponentManager::gc() that calls removeComponent() has
been removed because it's dangerous. removeComponent() is often
not enough, some additional cleanup might be needed.

Could we make FilamentAPI's destructor protected instead of individually on all the subclasses?

No, that doesn't help, because the destructor is still public: https://godbolt.org/z/7P19eWsP5
