Is anyone trying to tie users to multiple devices, and consequently identify both fingerprints as being from one user? I.e. Let's say I visit HN on both my laptop and on my mobile phone, each will have a very different fingerprint, but not only do I visit the same site on both devices but I am unlikely to do so simultaneously across the two devices, and there are likely to be other factors such as not visiting on either device during sleeping hours, not visiting on either device before some date (i.e. when I got into HN).

Perhaps you could call this something like 'cross-device fingerprint unification', idk.
