Very much in favor of this especially after discussion in
https://github.com/ThePhD/out_ptr/issues/19:
TLDR: "clever" contains a potential double-free and fix seems to be not
considered (or postboned) as it is "off by default"
Therefore having an unsafe, buggy class inside the library should not be
allowed.

Great point. I'd suggest to provide 1 implementation and let
customization points handle these "special cases". This will be a great
test on how to implement those using the "official" customization points
and whether the API is sufficient.
