It's not about having rare values, like the one user in a thousand with 32 cores. (That matters too, but it's not the main issue.) Fingerprinting is having data that persists for the user at all, such as whether a user has one or two or four cores, which are then combined with as many other data points as possible to create a fingerprint. Limiting the maximum exposed number of cores doesn't affect this. -- Glenn Maynard
