Neither do I, Randy.
I have seen recursive routing done - perhaps on a juniper - i really
cannot remember.
Given that the packet would be originating from the device itself (not
hardware forwarded), it would make sense that it should be able to
perform a recursive lookup. I'd put it down to an implementation
thing..

Unrelated, I was doing some thinking about a multihomed site and using
BGP advertisments sent out one link (provider 1) to influence the
sending of the advertisments out of the other link (provider 2). Long
story short I needed to know how long bgp nlri's take to traverse the
net, and subsequently have a paper that you co-authored open in
another tab - well done! :)
