Yes, but wouldn't you *want* to, for example, be able to search for
a particular error message that is no longer on trunk?

Especially since svn doesn't have "svn grep -r X:Y"[*], this seems like
a small price to pay (a little bandwidth every now and again) for
such a feature.

Also, while that would be true for a dumb crawler, many crawlers these days
are anything but. They should be smart enough to notice the ETags/Modified
Times/etc and not need to refetch/reindex everything. If they aren't smart
enough, they'll be penalized (they'll have to eat the bandwidth hit on their
end too) and the market economy will kick in and force them to become
smarter.

[*] Wouldn't it be neat, though?
