The text before dirfd reads in current glibc:

In some situations it can be desirable to get hold of the file
descriptor which is created by the @code{opendir} call.  For instance,
to switch the current working directory to the directory just read the
@code{fchdir} function could be used.  Historically the @code{DIR} type
was exposed and programs could access the fields.  This does not happen
in @theglibc{}.  Instead a separate function is provided to allow
access.

I think this is sufficient, if you disagree, please explain better what you
want to have changed and reopen the bug.
