Is there a compelling reason to enable it by default?

yup, the idea is to ship a de-cluttered and straightforward browser. however we figured there was no reason to completely block users from using Sync, so we made it easier to enable and added the faq entry for those who like the convenience.
it's just another option, like xbrowsersync and manual backups.
