Great Post!
This is so relevant stuff.
I never really understood why WP, especially in recent times where performance has such an impact on the web, never put something like this on core. Or, even better, why the WP installation doesn’t come completely clean and light.

And now, where the creation of websites/apps with it’s becoming less code/developer intensive, it could be even more a core strategy.
I will definitely install this in all my sites - congrats to the authors.

And a big thanks to you for discovering these gems and for testing them to the core bones - something I don’t really know how to do and always makes me anxious before installing a new plugin.

About automatic updates, they are essential, they should always be on. But they can cause damage. Why isn’t there a way, in core, to rollback to a previous stable version?
Maybe there could be a log file (last to be read on the site, to see if everything is working?) which keeps track of all installations (core + plugins) and sends a message to the admin if something is wrong and with a “click here to restore” option - it could even have different restore points according to latest installations?
Probably this isn’t possible or it’s a nightmare to develop but it sounds good.
