Is The Storefront_Rest_Api Addon Used Anywhere?

I was referred to this hidden addon before when I asked about adding to a cart through the API, it's very useful. But I want to add some customizations to it, so I was wondering if it will affect something if I change the code. Is it currently being used in the CS-Cart system, or is it just there for 'in case someone needs it'?

This module is used by mobile application

Oh, the 'official' mobile app of CS-Cart? So if we don't use that or we're building a different app, it should be okay?

Right
