There is no doubt that setting ICMP rate limiting per node in a router with both slow and fast interfaces to accomodate one interface may be very detrimental to the other: imagine T1 and 1Gbit Ethernet interfaces; 1% of a T1s 1.5Mbit/sec is 15kbit/sec, which is 0.00000015% of a 1Gbit/sec, and 1% of a 1Gbit/Sec is 10Mbit/sec, way over 1.5Mbit/sec.
You may have an assumption that the rate-limiting would have to be a
percentage of the interface speed. That's (IMHO) a bad strategy,
exactly why you describe: it doesn't handle fast/slow interfaces
appropriately.
This is a misinterpretation. Essentially I am saying that identical rate-limiting parameters (N,B in draft terms) on slow/fast interfaces would not handle ICMP traffic appropriately.
(However, you could limit the upper bound for token bucket based on the interface speed, I guess.)
Rephrasing your statement using draft parameters terminology, that is, N=average rate of transmission, and B=upper bound of transmission,
you're agreeing that Bx for a slow interface "X" should be different than Bz for a fast interface "Z".
This is good enough in support of the text suggested for the draft.
