That's a failure of the existing infrastructure to allow someone to do this.
LLM coding will work like this.
If you're letting LLMs go wild with no system in place to automatically know they're moving in the right direction and "shipping" things up to your standards, the failure is you, not the LLM.
The review comes at the end, though I truly believe this will go away as well. Agents will also get better at review until they're good enough that no one will want to do it anyways. Good enough is good enough.
It's like saying that you code reviewed faster just because someone else also reviewed the code, that's not how it works.
Its nice to not have to care about nits and other things that we don't have lints for though, so that's useful.
