I would ask what value the blue check has now that it's not tied with "actual" true verification of those of celebrity status? It's taken something that ensured credibility and that a person is who they claim to be and made it a novelty for any user just to say they have it.
It’s going to get additional features not available to the plebs. Also there might still be the “official” tag for blue checks that are authentic and companies/governments will have different colors. But yes it’s still going to be messy and unnecessarily complicated.
