A lot of people say this is a reasonable feature, and I agree (I would strongly consider having it on), but that's not the defense they think it is.

- Having the feature available seems good.

- Having the feature default on is debatable, but not outside the realm of possibility.

- Having the feature default on, without any kind of release notes that say that it happens and link to the option to disable it is clownshoes "bring back the ghost of Steve Jobs to yell at the product team" type behavior.
