SBD is not Betamax, it's a failed prototype that showed trees to be blue, the sky to be red, and human skin to be green. Also, there could be a fundamental shift in universal laws of physics in the next 10 years so that the above suddenly becomes true, but that doesn't mean the failed prototype shouldn't be canned today. You could say USDT is the VHS and DAI is the Betamax, though. One is overwhelmingly more popular, but both have done a reasonable job at holding $1.
If you want to see SBD live on, that's alright- but at the very least, the protocols need to be overhauled, or its purpose redefined.
