The discussions would be found in archive of tech-net on late April.

Since hostalias() is in the library code and it is not called
explicitly, hostalias() cannot know what uid/gid should be used
to check permission. Suppose the application may call gethostbyname()
even after it swaps ruid and euid.

I'm not objecting but we cannot find the answer for now.
