Having OS default be privacy addresses is certainly less damaging than
breaking end-to-end..

Personally, I think having the OS default be SLAAC and if you want privacy,
you have to turn it on is a fine mechanism. Users that care can educate
themselves. Users that don't care enough to educate themselves will fail
to assure their privacy in other ways anyway.
