As I commented on the “Site Health” article at wordpress.org – https://make.wordpress.org/core/2019/04/25/site-health-check-in-5-2/ – if that percentage score/graphic stays, then every site builder/plugin author/web host is going to need to brace themselves for the onslaught of site owners who believe that if they don’t score 100% then there’s a fault that needs fixing, and the resulting wasted man hours spent either applying fixes to non-problems or educating site owners in complex technicalities.
