I think the main problem with this approach is the all-or-nothing problem. When reading official docs is not always clear when you already have everything that you need. Reading the whole doc is usually not a possibility considering most modern tools have easily 100+ pages that go down the rabbit hole. In short, good official documentation is scarce and time to read is even more so.
