Interesting that the list includes "not being a lone wolf" and that goes on to state you should be capable of doing pretty much everything necessary to complete a project on your own. If you're capable of working well in a team you don't need to be able to do all the things in this list. You can hand off things to people who are better at those things. That's a good skill to have. That makes you very employable.
A good team member plays to his strengths, but a wide breadth of ability is still valuable. It means you can understand what your teammates are doing. It's not requisite and sometimes is unreasonable to expect in multi-domain projects, but that doesn't mean it isn't valuable.
Similar to philosophies on management. A good manager does little hands-on work himself, but he will generally make for a better manager if he could hypothetically fill the shoes of each of his reports. Not that he should ever actually do that, but it means he understands what they are doing.
