I'd argue that the responsibility to not pass `NULL` as the value for the
relevant parameter lies with the caller, not the underlying implementation.

In my opinion this certainly is one of those functions where passing `NULL`
does not make a lot of sense philosophical speaking, and I am semi-against
adding checks that simply protects something from invalid usage (instead of
explicitly saying that such usage is ill-formed/undefined).

Nonetheless, I'd be happy to sprinkle a few `assert`s related to arguments
passed, and update the documentation to make it more explicit about the
pre-conditions of using this (and other introduced) function(s).

  - Do you think that is a suitable middle ground?
