Is leaded gas still a requirement, or have they found a way around that by now for old prop planes?

It was caught in FAA-Bureauctatic hell for 15+ years and just approved last year. It will be still be slow to become available and adopt for reasons that are complicated, but amount to bureaucracy, economics, and an insane degree of risk aversion. The vast majority of pilots want unleaded and it’s also much better for the engines.
