As someone who builds reasonably large web apps for a living, this list doesn't really address anything that's specific for large scale. Separation of concerns, a common API layer, tests, linters and etc are the baseline of good development today, not something to consider only for bigger projects. What I've dealt with over the years, and would've loved to see addressed, is questions that are actually specific to projects at scale. Having hundreds of views, how do you classify and manage components? How do you manage shared components? How to achieve (and keep) architectural consistency across thousands of components? How do you address death-by-a-thousand-cuts performance regressions in big web apps? And so on. Sadly, this article doesn't address any of these.
