Documentation, like code refactoring and unit tests, don't directly add value for the client. Most companies don't place a high emphasis on these.

Isn't that a weird thing? Every recruiter post I'm seeing talks about how to write unit test, write clear comments, choose methods (functions) name with care, document your code even if it looks silly and again write tests!.

It's like what everyone wants, but then neither needs...

It seems as absurd to me as constructing a building without laying down foundations and having proper blueprints.

This is the perfect analogy - people might choose a house based on its size or its location. But nobody buys a house because it has strong foundations. Not that foundations aren't important, mind you.
