Going throught the demo store https://venia.magento.com/ and installing the headless version with our production instance it seems a lot of basic features are still msissing with PWA Studio provided by Magento an Adobe company now.
They have it as a major highlight of their list of major features as well on Version 2.4.2. You'll be able to see this on this link: https://magento.com/products/new-releases
However it's very clear that the PWA implementation lacks a lot of features already present in the Luma theme. This project has been running since 2019 and it's very frustrating as an enterprise client that Magento teams asks us to go through a 3rd party agency to have a workable fully featured PWA website in production when we are paying tens of thousands of dollars a month on license fees.
Putting up my question as a open discussion on PWA Studio and it's production readines.
