Why would I bother enabling both if XYZ plugin is already doing that, especially if the benefits are minimal? This is a fair point, however let me give you three reasons why you should enable the feature!
Removes HTML Footer Plugin Branding
Some plugins add comments into your site’s HTML. This means they put some sort of branding HTML comment in your footer. This is ultimately annoying and quite pointless. For example, many plugins that are responsible for optimization are also responsible for adding branding in the footer. This is annoying because you are either stuck trying to see if they have a filter to remove it or you have to live with it. CloudFlare’s minification tool removes this.
CloudFlare’s optimization features takes care of these issues and keeps your sites files clean. It has never caused any issues for me on sites I have used it on. Albeit, it could be more powerful, but that’s for a future post.
If it does cause an issue, you can simply disable the feature in CloudFlare.
