If you never reuse an address, all of this concern goes away. Spending any funds from an address means spending them all, and then any private key leaked no longer matters.

That's not actually true, as most private keys are deterministic produced. Leaking one key from a HD wallet leaks them all.

Leaking a single private key does not leak all the private keys. You would still need the chain code used to derive all private keys, no?
