Some sites use CF DNS just to have the ability to spontaneously switch on the proxy at will. They tend to keep the proxy turned off but then when traffic peaks a bandwidth detection mechanism switches on CF proxying. The problem with that is users don’t know from one click to the next whether their traffic will be intercepted. It can happen at any moment. So the deCloudflare project treats CF DNS cases no different than always-proxying sites.
So if you have no intention of using CF’s proxy, using a non-CF service would make more sense so your domains don’t get treated as CF. CF is not a good company to support anyway.
