Some game engine developers have certainly used this idea, to prevent any reallocations when the dynamic array needs to be resized. Such as: https://ruby0x1.gi

Some game engine developers have certainly used this idea, to prevent any reallocations when the dynamic array needs to be resized. Such as: https://ruby0x1.github.io/machinery_blog_archive/post/virtual-memory-tricks/index.html https://ruby0x1.github.io/machinery_blog_archive/post/virtua... Some ECS implementations use this to reduce the overhead of dynamic arrays, as well as ensuring pointer stability of the items stored. For example entt: https://skypjack.github.io/2021-06-12-ecs-baf-part-11/ https://skypjack.github.io/2021-06-12-ecs-baf-part-11/ And here's a library implementing a resizable, pointer-stable vector using virtual memory functionality from the OS: https://github.com/mknejp/vmcontainer https://github.com/mknejp/vmcontainer
