The product I linked is 116 octane and is unleaded and does not contain ethanol. I am not exactly sure how long it's been on the market but doing a simple search I can find people referencing it all the way back to 2017. So at this point even for super high octane needs there is no requirement for running a leaded gasoline anymore and hasn't been for some time.
