Ha! The HN feature of emphasizing comments and de-emphasizing their authors worked too well. I did not notice I was replying to the original author of Mithril. Hi Leo.
If "long copy sells" is the reason why feature creep leads to marketability, then maybe an abundance of examples would help.
They are (and FWIW, the Stroustrup quote[1] is quite applicable here). I'm merely pointing out that feature creep leads to bloat/complexity which lead to people to complain, and that feature creep also leads to marketability (which is a reason why mainstream language spec documents typically have hundreds of pages). Personally I think this pattern is a problem, but I don't know if anyone has managed to figure out a solution.
