Deprecating it may be usable, yet I don't believe we can easily enforce
such a policy [1]. Have you looked at how many (potentially) unsecure
uses there are in the kernel, to give an idea how useful such an effort
would be?

[1] Unless we'd go through things like Visual Studio's
    #define strcpy __strcpy_unsafe_use_string_cb_copy stuff...
