Even better some developers have even been brainwashed into thinking Scrum is for their benefit!
Engineers have so much on their plate fighting the actual code that making them talk to users (who don't know what they want half of the time or are involved in some sort political battles themselves) is just putting too much on their plate IMO. Maybe this could work in a smaller organisation with a fairly straightforward business, but in any place old and large, there's usually so many stakeholders involved (usually playing poor man's game of thrones amongst themselves) and so much random conflicting bullshit (in the requirements etc.) that any sane developer would be happy to just be oblivious to that.
Very few organisations are willing to work like this because nearly all project- and middle-management would be out of jobs. The management class will always strive to protect itself and its members from the workers (both end-users and devs).
The spec only becomes inane gobbledygook when filtered through a PM who doesn’t understand it but rewrites it in business-speak anyway, or an “architect” who also doesn’t understand it but thinks it needs to be a grand, generic solution.
