Why is UUCP Notoriously Unreliable?

I believe "ihnp4" is running the famous "honey danber" UUCP; this is
available from AT&T with the "Basic Networking Utilities" package (whether
that's just a binary package for the 3Bs, or an add-on source package for
all systems like Documenter's Workbench is, I dunno).  With any luck, it'll
be the standard UUCP in some future S5 release.  This UUCP has an extra
"control card" (or cards) in the X. files which tell it how to return
undeliverable mail (I don't know what it does about arbitrary UUCP jobs).
