@carlton I don't think they're directly comparable.
Django has a canonical set of official docs to refer back to, as well as the code itself. Many tutorials are written to make those things more approachable, or tie multiple strands together in ways people may not find obvious. The information quite often (though not always) does already exist elsewhere, and that state of affairs provides a nice progression story for people wanting to dive in in more detail.
In accessibility, a lot of the literature out there is reactive rather than proactive. I include WCAG in this, which many people might point to as a canonical work. But in truth, it was written as an attempt to make sense of very messy things and get them down in writing, but the scope is extremely limited (and quickly becomes outdated). And with less content overall, there are less opportunities to cross reference.
That last point might sound like I'm encouraging more writing, rather than less. But there is a huge imbalance between "basic" topics that have been written to death, and more advanced ones that have zero resources (mostly because people get paid to consult on those and don't/can't write anything down).
