Hmm I'd agree however I don't like to not have any (non-link-local)
addresses when there is no uplink. So I think I will keep the current
workaround (announcing ULA with preferred time 0 as long as there are
public prefixes) and see how that works.

Yes, I wholeheartedly agree with you from a technical and ideological
standpoint. However I don't think it would be wise - at least as an
OpenWrt developer - to force any of this ideology onto users. IPv6 NAT
made it into the Linux kernel so I guess there are some legitimate
use-cases, so at least I don't want to be the guy assuming I know better
then the people who implemented, requested and accepted these features.
I'd rather have it implemented and more or less supported in the most
sane way possible then people hacking it in on their own.
However as I said I feel the need to have reasonable defaults and make
it easy (easier?) to use the standards-compliant way than to use NAT.
Thats where I can be reasoned with ;)
