This is why I don't want strict. That and true-positives, I don't think
having a switch that allows courts/rir finger trouble etc to take out
global routing is sensible. Too many others would start using it.
However loose mode could be abused in the same way, they just
invalidate your key and advertise a covering route to give themselves
effective strict over you. Admittedly there is collateral damage to
adjacent address space incurred in doing this but we know there are
hijack techniques they could use to mitigate that
