How do you quantify "new code" - is it by lines of code or number of PRs/changesets generated? I can easily see it being the latter - if an AI workflow suggests 1 naming-change/cleanup commit to your PR made of 3 other human-authored commits, has it authored 25% of code? Arguably, yes - but it's trivial code that ought to be reviewed by humans. Dependabot is responsible for a good chunk of PRs already.
Having a monorepo brings plenty of opportunities for automation when refactoring - whether its AI, AST manipulation or even good old grep. The trick is not to merge the code directly, but have humans in the loop to approve, or take-over and correct the code first.
