Yes, they went in a few weeks ago too :) ( there is one patch outstanding 
though)
current released quagga cannot handle ifindex in the LSA(like BIRD do for /32 
masks).
This is an old defect in Q. so BIRD is not to blame.

Yes, a /32 mask is not a "proper" prefix so you are quite right. What to
do with these varies in existing ospf impl.
