Why do you say that feeding back an output (internally within the part) isn't
ideal? With most of the smaller PLDs, the routing is pretty staightforward
(and fixed!) so it's reasonable to just build your own using the AND-OR array
within the part.

I haven't use any non-in-circuit programmable parts in years now; I'm amazed
that anyone still does.
