HN is a bubble for sure, but that may not be the reason why low-code tools are not discussed. Suffice it to say that my interest got less and less piqued with every single word in the URL you provided (I was already biased against it before even reading the report), and I couldn't get past the first few pages in the PDF before feeling bored.
I recently was looking for Java based open sourced wiki software for intranets. And I read about this software called LifeRay. To most people on these forums, LifeRay is not particularly interesting (based on searching HN for LifeRay related submissions and seeing how many comments a submission gets). The market size for LifeRay might be quite large, I don't know, but it is just not the kind of tech that people are excited enough to comment about. For example, I am fairly sure no one is going to go and read about LifeRay just because they read this blurb.
There are many different reasons for the lack of excitement as I am sure you can imagine. But the echo chamber is not the cause of the lack of discussion. Some topics are not just interesting enough, and probably never will be.
The link i gave is to a report. It's boring. But it's comprehensive and lists all the platforms and a good starting point, because someone asked about that.
But the issue itself is more interesting: first - it's a big and relatively common software design problem(for example see how often visual "coding" is discussed) - how to enable common people to build complex systems. So what are the approaches being tried ? How are the better/different/worse/etc ? what could we learn from them ?
Second - what does it mean to the software engineering profession ? to freelancers ?
Third - what are the implications to entrepreneurs ? what kind of new opportunities does this open ? could this make large corporations agile enough to make it hard for startups ? what are good strategies ?
On the other hand, often you see here discussed some toy programming language that someone made(which is a cool project), but the improvements are quite small, the implications are quite small, and the major reason people find it so interesting is the bubble.
