Kind of frustrating to watch indeed. Have similar complaints for GUI apps on the desktop, really feels we went backwards from building great GUIs in 10 minutes using WYSIWYG to never really seeing the GUI until it compiles a bunch of XML and you somehow hope it will match what is needed.
Productivity is now wasted trying to make sure that buttons work when pressed or scratching the heads why box is not aligned with another programatically.
You mean many developers want. Actual customers, the ones who pay for your work don't even know what Next.js is and are extremely happy with whatever works. The hard part is to sell the idea that - no, next.js is not the best for your SEO heavy website :)
It pains me that so many SaaS go for Next.js based SDKs, but at least it is the closest to Spring/Quarkus/ASP.NET in spirit.
