> I am somewhat dismayed that contracts were accepted. It feels like piling on ever more complexity to a language which has already surpassed its complexity budget, and given that the feature comes with its own set of footguns I'm not sure that it is justified.
I don't think this opinion is well informed. Contracts are a killer feature that allows implementing static code analysis that covers error handling and verifiable correct state. This comes for free in components you consume in your code.
Contracts aren't for handling errors. That blog post is extremely out of date, and doesn't reflect the current state of contracts
Modern C++ contracts are being sold as being purely for debugging. You can't rely on contracts like an assert to catch problems, which is an intentional part of the design of contracts

Asserting that no one wants their code to correctly handle errors is a bold claim.
