Hmm, well the events are there, the kernel could remove the connected
routes. I suspect it's more to do with possible breakage that would
occur with non-link-running aware apps that expect to be able to send
packets out a specific interface by specifying the appropriate
connected address, possibly.

Could do that, yes.
Note that OSPF, for active links, already takes care of dealing with
dead-but-up links in the protocol.
