Yield Aggregators: Value Add or Just Another Layer of Risk?

I've been thinking about the true utility of some of these yield aggregators and auto-compounders in DeFi. While the premise of optimizing returns is attractive, especially when you consider gas fees, it feels like adding another layer of smart contract risk and potential rug pulls that might not always be worth the marginal gain. Are we collectively overestimating their 'set it and forget it' simplicity, or am I missing the fundamental value proposition beyond just convenience? Would love to hear some counterarguments on why the risks are justified for current yields, particularly with $USDC trading tight at $0.99975.
