To me, this list describes a unicorn. Not surprising since the list was generated from job descriptions. These are desired software dev qualities, not actual observed ones.
It’s hard to recruit for these capabilities but you can see them over time in someone who’s on board.
And indeed, no person is optimal on all those dimensions, and people change over time. But just as in engineering, it’s a trade off (I need a material that is strong, light, machinable and within budget) so you prioritize the feature set you require.
Also you likely have a team, so you don’t need a unicorn but instead consider these the characteristics of the team. This is also like engineering: this part is not load bearing so I can optimize for lifetime/flexibility/cost and have the load bearing part be strong but heavy.
