I want to say this is good, but if you look at the "exemptions" for when law enforcement wearing masks is fine, it covers basically any and every possible scenario. So to me it just seems a performative act to make it seem like they are doing something while doing nothing at all.
Historically, establishing a right with exceptions then subsequently eliminating those exceptions has been effective method of effecting change in the US government system.
E.g. the famous Marbury v. Madison decision that effected no action in that instance but substantially shaped the relationship between the branches by establishing the federal court system's power of judicial review
