Automatic updates is absolutely a tradeoff of risks. That’s where being able to selectively enable automatic updates helps site owners balance those risks. A plugin like this is a good candidate for auto-updates since emails can be a higher-risk target for security vulnerabilities. Others, like a plugin that only does visual changes to the site may be a higher risk of breaking the front-end and lower risk of introducing vulnerabilities – leaving auto-updates off might be safer in that case.

I personally believe the introduction of auto-updates to WordPress as an opt-in feature is an absolute win for the platform.
