What would that change? If you're legally required to make people wear masks when they enter your store you can't just say "oh, but there are these peeps who said that they already had the virus, they said they could be identified by their green wristbands, I will let those in without a mask". Local law enforcement will first laugh at you, then threaten to close your store if you don't comply with the law which does not exactly include a paragraph about exempting people due to whatever kind of self-chosen fancy "survivor IDs".
