support for multiple addresses is IPv6's Achilles heel. they need to be tolerated to make renumbering work, and LLs are indeed useful for bootstrapping, etc. but expecting multiple addrs to solve the routing scalability problem (just to take one example) was a grave error. I'm all for consistent behavior between implementations, but we're deluded if we think that default address selection is going to magically make the problems that come with each host having several addresses of varying scopes/connectivity/lifetime disappear. no set of default rules can cope with that complexity. that and the current rules are broken because they favor scoped addresses over globals. scoped addresses should never be used except as a last resort.
