BIRD definitely did not ignore interfaces with /32 mask, (for example,
you can have BGP or OSPF link with peer addresses without any problems).
But if you just add IP address with /32 mask (without specifying a peer
address) and then add a device route for some other network, IP
addresses from such network are not considered to be neighbors. I am not
sure if that answers your questions.
