I would be shocked to hear that certs bound to IP addresses are being used
in significant enough number as to be untenable, but your reply here
definitely sounds like it's in the "It's work and we don't want to do work"
side of the camp, not that it's fundamentally not viable. Given the risks,
and the ecosystem harm done by carving out bits of RFC5280 where it suits
customers who don't want to do work, rather than provides positive security
benefits, I think such requests should be treated with great skepticism.
