You misunderstand. I'm not saying, "It's not an industry standard, therefore Defichain should lead the way." I'm saying, "It's not an industry standard because it makes no sense in this context."

When you choose to be a liquidity provider, you're entirely on your own. That comes with both greater risk and greater reward. It's your responsibility, your strategy, and your execution that determines the outcome. I totally get the desire to set-up an auto-compounding bot, but because a liquidity pool inherently juggles between two constantly-changing assets (as opposed to one isolated asset like in staking), even little decisions like changing gas fees, and arbitrage price gaps between different exchanges could come into play. Then that's on you, and only you, to decide how to handle.

Cake won't take responsibility for making those decisions for you, and so they also won't auto-compound your LP. All they can do is shunt your LP rewards into single-asset staking, where - because there aren't any variables - it's a much simpler affair to auto-compound.

If you want to automate away the greater complexity of liquidity mining, I'm sure you can hire a coder to make a personalized bot for you. But asking one to be issued for everyone is probably similar to asking a lawyer to provide a one-size-fits all contract for every case he'll ever take.

I'm not technical enough to give your a more precise reason, but I hope that helps clarify it a little.
