Hi Alex, I remember when the idea of having SET and ADD do the same operation <https://developers.google.com/adwords/api/docs/guides/extension-settings#adding_ad_extensions> came into being, so I can shed some light on it. From a coding perspective, people found it cumbersome to have to have to do a get() to see if something already existed before deciding if they needed to do a *SET* versus an *ADD*. That was an extra operation, and when you're doing a lot of these, it adds up. It was easier for people just to do a *SET* no matter what. The API could then figure out for them if it needed to be an *ADD* or not. There were fewer calls to the API, and it made the performance of people's applications that run against the API better as a result.
Batch processing does allow for you to create an object earlier in the job, and then mutate it in some way later on in the job. It does rely on that ID. Now, we do recommend against doing that in our Best Practices <https://developers.google.com/adwords/api/docs/guides/batch-jobs#best_practices>. The reason we recommend against doing that is because of performance and also that we don't guarantee the order of all the operations. That means some of those mutates() of the newly created object may happen in a different order than you would expect. I hope that clears it up for you!
