Who thinks it would be a "good idea" to have a knob such that ICMP error messages are always source from a certain IP 
address on a router?

It certainly would beat the alternative of no response at all,
but one would hope it wouldn't become common practice
since it reduces the information returned (e.g. during a
traceroute, you'd lose the sometimes useful information
from in-addr about what particular interface was involved).
