When a game is in Early Access, it doesn't make a lot of sense to put a massive amount of effort into the user-onboarding experience, because it will constantly need to be changed/updated/etc. as the game development progresses.

Expecting an Early Access title to do a phenomenal job at that is actually foolish, because that constant need for it to be updated takes away from development time on everything else. In other words, it makes the most sense for that to come late in the process, shortly before final release.
