Obviously, camera usage is different per user (some users don't use this or that feature, some others don't bother - for example, I absolutely don't bother about Astrophotography or Cinematic recording but it doesn't mean these are not important).
The fact is that many people do use these features and we can't just ignore the fact that these issues do not exist - camera is one of the major features of flagship phones and it should just work - especially, when it is mentioned in GOS FAQ that Google Camera does work. Many people use camera heavily on daily basis, taking multiple pictures pretty quickly, etc.
At the end of the day, we are using a flagship Google phone not just an average cheap Android phone. Google Camera does work flawlessly in stock firmware so its not a hardware limitation.
It simply shouldn't take over 40 seconds to process a portrait picture and all should be smooth like in any other modern phone. Try taking 3 Portrait pictures in a row - boom, Google Camera will stuck forever processing these pictures and won't take any more pictures until it will process all these but in stock OS it takes a blink of an eye to process so there are clearly issues that we cannot simply ignore.
Imagine a prospective Pixel 7 Pro buyer - they have no idea Google Camera won't work as expected as it says in all GOS FAQs that it works with GOS services. They are buying the phone and then Google Camera doesn't work as expected. They will surely ask why this info was not acknowledged or provided in FAQs as otherwise they would not probably buy it, correct?
I don't blame GOS at all as Google Camera is not their product (and GOS is a great OS!) BUT this issue is something that needs to be acknowledged and probably written in FAQ so that people will know what to expect before buying the phone (this is the reason of having a detailed FAQ).
We can't just pretend the issue doesn't exist or exists like a very very minor bug - it is a major thing, indeed.
