It's freaking kubernetes, so obviously it will be a well understood file by a LOT of people. However this is the kind of file that also exists in unknown, non-open source products, and while may have been understood by lots of people (at the respective companies) sometimes a period of 5 years of inactivity and layoffs and hiring goes by... By gosh darn it- this is it. It's the reason we have shitty code but great products.
