I was referring to prediction markets. As for CTV, I don't have enough knowledge to form a well informed opinion.

CTV is what you want to see or the prediction market thing? If the latter, I think it can already be done.

I believe that this technique generalizes to any opcode that replaces an OP_NOP in P2WSH.

And it seems like it could be useful for any soft fork that proposes a new opcode.
