Summary ResolutionMediaFeatureEnabled is a no-op

Since bug 248619 removed the (already dead) legacy media queries code, the ResolutionMediaFeatureEnabled setting has had no references within WebKit. While dropping this setting is probably fine, we shouldn't have the setting hang around while it does nothing.

I wonder if we should reinstate this pref, I assume it was added to prevent fingerprinting. Though a better approach to prevent fingerprinting is to spoof this + other relevant vectors to 1x.

No, it was added because it provided a path to enabling it in WebKit (versus the ~decade it had been behind a compile-time flag) and because we for a while had quirks that disabled it.
