I proposed an environment variable to solve the following issue: when memory allocators are replaced with custom allocators, debug hooks cannot be used. Debug hooks must be set before the first memory allocation. Another option is to add a new function (ex: PyMem_SetDebugHook()) to install explicitly debug hooks, so it can be called after PyMem_SetAllocators() and before the first memory allocation.
