Root causes wise, my impression is that software language engineering has a knowledge integration and communication problem. Lambda the Ultimate doesn't have a wiki. :) Academic papers provide a foundation, but a lot of practical professional knowledge is scattered, siloed in language communities, and time-consuming to access. Gathering best practices for language design and implementation isn't something we do well. So language creation projects often look like team and/or community "learn by doing" education exercises. Even with good people at leading companies... I had a conversation at redacted once, "why did you make (disappointing) design decision X?", "mumble mumble", "<facepalm> that's a (widespread) misconception, a misinterpretation of paper P (which admittedly could have been clearer), that's been kicking around for several decades now".

My fuzzy impression is the npm repo was not originally a mission focus, but rather a "don't be python" add on goal. Absent organized best practices, low-priority design decisions are often not made well. Perhaps Ruby, Perl5, and/or Python were copied, without attending to those communities experiences, and the implications for an even more fine-grained code sharing community.
