This go thin with uv is good advice for smaller projects. But as you grow with more aspects, it gets more problematic.

I ran code that way for years. But now we have 23 different services: web apps, APIs, and database servers, my code and other self-hosted services.

I would NOT run 23 projects/servers (3 versions of postgres) this way. Like so much, it depends. FWIW, the book goes into depth about these trade-offs.
