What makes you reach this conclusion (for third-party packages, not for
some well-maintained GNU packages)?  Why was there a need at one time
but not now?

CVS Libtool's libltdl allows third-party user code to decide over the
naming of the config header file it may share with it (and whether to
use one), thus the weird usage in lib/argz.c.  I don't see a compelling
reason to drop this support.
