I put my team through this as an inexperienced lead about 15 years ago. We were a team of less than a dozen who had a nice single solution file that you could build and run the entire stack from. At the end we were looking at roughly a dozen services all which required orchestration to get them running and working together. First hand lessons in YAGNI and "do the simplest thing that works" which have stuck with me the rest of my career.
