have any bridge descriptors yet, would we fall back to asking the bridges
for their own descriptors, or would we just break?
If you set that flag when launching requests aimed at the bridge
authority, and Tor can't build circuits, those requests will fail. That
shouldn't interfere with asking the bridges for their own descriptors.
If you set that flag when launching requests aimed at the bridges
themselves, and Tor can't build circuits, those requests will fail, and
Tor will thoroughly break. So don't do that then.
