If nothing else, it showed everyone the potential of taproot. There are fascinating possibilities, for sure.

I read an interesting idea: rollups (ala taproot) used as a test bed for changes to the code. Sure, there’s testnet, but testnet never actually interacts with the Bitcoin incentive system. The unintended consequences of a change the code are difficult to predict, and not fully tested in testnet. So, if you encode a bitcoin virtual machine in taproot and add a possible change to the code, you can see how the market adapts to the change (if at all). Interesting if that could be pulled off.
