As long as there's a switch to turn it off, you'll be just fine. Meanwhile millions of poorly monitored sites will be less vulnerable to attack at the cost of what I suspect will be relatively infrequent update snafus. All security is a tradeoff and this is a good one.

I just updated a test site to 3.7 and I'm not seeing anywhere this can be turned off.

Found it! In order to disable it you have to add define( 'AUTOMATIC_UPDATER_DISABLED', true ); to your wp-config.php file
