As I understand it, almost all anti-fingerprinting protections are some measure of this, balanced against the level of breakage to accept. For example, Firefox is able to "letterbox" your viewport, i.e. restrict its size to one of a number of preset ones, filling up the remaining space with grey. That reduces entropy, but makes the user experience considerably worse, so it's not enabled by default in Firefox. Something like Tor Browser has a higher tolerance for breakage, so it does enable it.
