yes and no. As long as you are able to get a globally routeable ipv4 address for your home at a reasonable price, no. Once you start being subjected to CGN (either or your end or on the remote end) or the price pressure of IPv4 in your region then you will have a reason. Namely cost and performance.

Because of this I would suggest that if you go router shopping that you should choose a model that supports IPv6 rather than not, even if you don't necessary care which you will end up using. Get a model with a good IPv6 firewall that you can tell to block all incoming connections.

Lastly, I think it is dangerous for "casual users" to say things like "I don't care about direct addressing of devices at home". I firmly believe that universal direct addressing will result in new innovation that might change your mind. :)
