> If people think this is too complex,

I don't think it's complex, I think that it might be difficult to
integrate in an existing implementation of ICMP.

Different ICMP implementations have different behaviours.  A router vendor
who wants to implement this draft will likely want to minimise the amount
of changes that they need to make to their implementation of ICMP; if we
constrain the behaviour too much, the amount of changes will likely
increase, which in turn might hamper deployment of the protocol.

I therefore agree with David that we should aim for the least constrained
description that still ensures that PMTUd isn't broken.
