Point D is a thing we assume about software but over time you realize it's not the case. You'll see a native macOS app like Terminal and assume it's blessed by Apple, has its own dedicated team with daily standup and meetings, but it's actually just propped up by random tickets in a larger issue tracker, doesn't have a dedicated team, and depends on what amounts to begrudged work or charity work by whoever happens to work on a ticket in passing.

A random rockstar will come in and move the code forward 5 years never to be seen again.
