I think you have it backwards - Cloudflare et al would want to allow the typical user and block the oddballs. That said, it's a further misunderstanding with utilizing such tools in general. Unique is neither good nor bad on its own. The next question is "always the same unique because that's all you share or always unique because certain fingerprintable attributes are randomized over time/visits/sessions". I.e. it's a war between trying to fake an average enough fingerprint and trying to track someone through partial matches, not just a matter of "is the fingerprint unique".
