Comment (by pento):

 I'm not wild about this. It seems like it'd involve a lot of churn in both
 core (if we're providing this, we should use it), and in plugins, for when
 their minimum version catches up to this.

 The only thing it prevents is clobbering $wpdb, which you're going to
 notice pretty quickly. It doesn't prevent more subtle errors which are
 harder to catch. (For example, changing $wpdb->charset.)

 Also, is this proposal just for $wpdb, or all of the globals WordPress
 provides?
