I would even say there's a type of comment along the lines of "we've been adding Roentgens for decades, surely adding some more will be fine so stop complaining".

As a second-order effect, I think there's a decline in expected docs quality (of course depends on the area). Libraries and such don't expect people to read through them, so they are spotty and haphazard, with only some random things mentioned. No wider overviews and explanations, and somewhat rightly so, why try to write it if (nearly) no one will read it. So only tutorials and Q&A sites remain besides of API dumps.
