Well, I'm doing a careful, slow rollout of v6 in an enterprise. Things
like this can be herded so as to be way below the threshold of noticeable
for 99% of the users. The only quirk we've found is a LAN that first
got v6 and then lost it (long story of IOS upgrades enforcing sanity and
breaking hackish deployments). Clients on other segments were a bit upset.

IMNSHO, the API is not as defective as you might think. The idea was to
replace v4. If we cling to v4, what is going to happen? (Well, ask just
about any ISP except HE and a few others, they can tell how it feels to
cling to v4 and go LALALALALALALACANTHEARYOU when customers ask for v6)
The happy eyeballs fix is of course convenient, but only necessary when
the network is so broken for v6 that you should not have turned RA on..
