Completely agree on being conservative. This is why no one is rushing OP_CTV, it's been carefully reviewed over the last 4+ years.

It hasn't been on litecoin but it has been on something better which is bitcoin's signet (like bitcoin's testnet) for over 18+ months with a 5 BTC bounty for finding any bugs.

You can experiment right now, look up sapio and start creating some contracts.

Remember again we're just trying to reach consensus on when to upgrade since the technical discussion is mostly over. Currently 2-4 years from now is being thrown around.
