If you enable IPv6 you reduce not only number of packets you can process. You reduce number of routes you can process, etc. And about <1%... this is red herring: if the IPv6 traffic is <1% and you expect to have at on this point for a long time - then why bother (do you really expect significant revenuy from this <1% traffic?), but if you expect that this proportion will grow then IPv6 support means real money. The best alternative is to prepare contingency plans and wait till they will be needed - and this is exactly whay most ISPs are doing.
