Every team has a tech lead (or a most senior dev, or architect, or whatever) whether they formally assign one or not. Titles are nonense but so is the idea that roles don't exist.

Regardless of the title (or lack of title) of the person, there will always be a person or a small subset of people that make technical judgements, communictate with management and so on.

I completely agree with the article that coaching, architecture etc. are different tasks and should ideally be different people. The reality though seem to be that it's usually just many hats for one or very few people .
