Pros and Cons of Disabling Rules for Software That's Not on the Server?

There are a number of rules that protect software we don’t have installed on our server, including rules for Drupal, Joomla and Magento. What are the pros and cons of disabling those rules if we aren’t going to have that software on the server?

We recommend to disable rules for applications which you not installed and did not plan to install on your web server. This would increase overall performance and reduce chance of false positives. But we would not recommend to disable common rules for all applications, e.g. “Global Protection”, “Bruteforce Protection”, “PHP Protection”, etc.

Thank you! That’s exactly what I wanted to know.
