Not sure I see the value of this.

Three additional jobs that run in series with our existing CI jobs and duplicate much of the setup we already perform doesn't solve any problem we have. This will just make CI take longer than it already does, which IMO is too long.

If we want to check the diff is clean for generated code, we can do that as an added step in our existing CI steps and it will add very little complexity and very little build time.

That make sense, I changed it back to only checking git diff.
