Wouldn’t you have to recompile all your dependencies or run into ABI issues? For example, let’s say I allocate some memory & hand it over to a library that isn’t compiled with fat pointers. The API contract of the library is that it hands back that pointer later through a callback (e.g. to free or do more processing on). Won’t the pointer coming back be thin & lose the bounds check?
