As Pekka already pointed out, all the three methods are provided as examples. The draft mandates the rate limiting by saying: "an IPv6 node MUST limit the rate of ICMPv6 error messages it sends" and then it provides examples by saying: "There are a variety of ways of implementing the rate-limiting function, for example:" So I don't think we will be doing anything bad by removing the bad examples. The Timer-based method does create an significant operational problem i.e. it breaks traceroute.
