I'm not sure if it will aid in fingerprinting, although it is more bits of uniqueness. Even with sub-week persistent I'm pretty sure that helps if fingerprinting is used to track movements between sites, like ad click through rates or for intra-site telemetry. Heck, resolution is still considered valuable for fingerprinting and that changes when people reorganize their desktops.

But beyond simply fingerprinting, it still is providing some tracking. I've seen a lot of "anonymized" data turn out to be not so anonymized in practice, or reversible to a large degree.
