Yes, but keep in mind that this particular issue has to do with an ASIC which is several years old and which contains other significant handicaps as well (viz. NetFlow caveats, no per-interface uRPF mode, etc.).

So, complaining about most anything on this particular ASIC isn't going to accomplish much, unfortunately.  The key is to a) evaluate newer ASICs on more operationally useful platforms in order to see how they handle this sort of thing (EARL8 should be fine, AFAICT) and b) put the appropriate requirements into RFCs so that vendors have a monetary value associated with doing the right thing.
