What this feels like to me, after a nominal amount of time using it, is that I am now in charge of vetting the proposed code, and is it appropriate for my use case, and does it meet our coding standards and does it integrate with my code or further suggestions. Honestly it feels like constantly code reviewing, which is not pleasant nor conducive to productivity.
And I do a lot of PR approval, and I shudder to think about PRs stitched together in haste because look how easy it is now to crank out code!
And lastely it doesn't work well when you have a large legacy codebase that your working within.
