It is very do able!
They have done it in the past up to this point. In the past we have even seen the incremental changes as the patch progressed. When the patches came out ZOS would do a consolidated one which would include the last minute changes. They missed things and I expect that but they would post updates just like they do on the standard patch notes.
The API jumped by three version. That implies in-house had seen and signed off for version control purposes. Why was those stages not shared? Part of testing is to give feedback on the game changes including the API. We had lots of discussions when the restriction to the API hit just before launch. They let us know then what was changing. I don’t understand their choice to not communicate API changes that effect add-on developers just because PST became truly open to the public.
