> What you actually need for a sufficiently complex financial life is input validation, and that's exactly the problem that plain text accounting software punts on.

Which input validation do you get in gnucash that you don't get in e.g. hledger? Asking as a hledger user. So far I mostly have assertions every month about account balances, and of course hledger checks itself that transactions are balanced. I avoid duplicating accounts (say expenses:something:stuff and expenses:other_thing:stuff) using autocompletion.
