I don't think IPv6 addresses are a nuisance. For instance, I bet you can't even tell me the IPv4 address of http://www.raspberrypi.org
without looking it up. (Or maybe you can because you admin the server, in which case I'll ask about elinux.org, Wikipedia or whatever.) If you don't remember the v4 address, why would the extra length of the v6 address be a problem?
And as I said, your own network will be dual-stacked, so even if you're on your local LAN and DNS is broken and you were silly and picked long addresses that you couldn't remember, you still have your v4 local addresses available too and can use those to get DNS working again.
There's just no advantage in jumping through hoops to remove IPv6 from your LAN, and a big pile of disadvantages (many of which are mentioned in the RFC that depreciated NA(P)T-PT.)
