This is 100% one of my favorite algorithms, but I have to say I've started to wonder if I just have an academic fascination with it and the practical use cases are more limited (limiting?) than I think
It is simple enough to understand without hardly any crypto background or advanced math. You basically just need a bit of algebra. It is surprising that it is possible at all. It has a clearly visible concrete use case (at least at first). It is something that you can implement yourself (though there are still footguns).
This, IMO, leads to its wild overrepresentation in discussion forums and even overrepresentation in industry solutions.

I don't think the linked post should prompt such wondering? (It's not clear if you are drawing a causal link between the two) It was an issue with the interface _to_ the algorithm, not with the algorithm itself.
I'm currently writing an entire book based on this concern: pmfpbook.org
