probably because that’s just not as fun, i would imagine a huge part of it is implementing everything from the low level to the high, and seeing how it all works together ^_^
Correct! It's fun to control the whole stack. And while I've been programming on POSIX systems for over 10 years, I've learned more about POSIX programming in the last year than in all the preceding years. There's no better way to understand something than to implement it.
And staying within a Unix-y paradigm means that if some part(s) become too good, they can be semi-easily ripped out and turned into portable libraries/programs instead.
