True. IPv4 router requirements recommends it, and it's standard practice
for routers. However:

It is clear that what is in -current and netbsd-1-5 right now is
extremely poorly tuned.
Itojun and I had a long discussion about this last month and
we didn't actually reach any code as a result, but I think
it made clear a number of thinsg that had to happen.
I will summarize it to tech-net and see what we can do about it.
If we don't have a good fix, personally, I think that turning it
off in 1.5 is better than leaving it on in this broken state.
Clearly rate-limiting localhost differently from other machines
is a kludge and indicates the limit is rather problematic.
