I wouldn't bother, unless you have many thousands of devices - but I must
admit I haven't crunched the numbers hard or built anything large enough
to see where the necessary pain happens.

Remember, at this point you've only got a fairly small number of routes in
your IGP, and they ought to be the most stable routes in your network, so
you're going to be running SPF both quickly and infrequently.
