Post author here. Two things I would add, given that the post is now nearing a year old:

1. Many people are unable to update to browsers which support the latest features, so developers must continue to practice “defensive CSS” for quite some time yet. Ways to do so include Sass, Lightning CSS, and PostCSS.

2. For those who know their audience is using updated browsers, be advised the nesting syntax is now more relaxed[0] and, like Sass nesting, generally *doesn’t* require the `&` stuff (which *does* still work, though).
