I can't list a relay in my EntryNodes if it doesn't have the Guard flag

In the past, I could do

src/or/tor entrynodes moria1

and voila, I would begin using my Tor with moria1 as my entry node.

In the new world order, post prop#271 I assume, I instead get this complaint:

May 08 20:27:42.394 [warn] Your configuration excludes 100% of all possible guards. That's likely to make you stand out from the rest of the world.
May 08 20:27:42.394 [notice] Starting with guard context "restricted"
May 08 20:27:42.405 [notice] Bootstrapped 80%: Connecting to the Tor network
May 08 20:27:43.425 [warn] Failed to find node for hop 0 of our path. Discarding this circuit.

and then I never bootstrap.

This is clearly a regression. Is it intentional, and I should go read guard-spec.txt for why, or is it accidental?
