Review comment:
> `wd_initialize` is defined as a weak, so the user is able to override
it with a custom initialization procedure. So, to a certain extent, this is a
breaking change, isn't it?
>
As I understand, the weak used here want to avoid the linker bring the
unused code/data if nobody call wd_xxx function, that's why the code check
wd_initialize before invocation.

The better approach is modify wd_initialize directly.
