See my comment above - it's greenfield projects too. Company I work for had a nice .NET Core / Gatsby React set up with reasonable Microservices on Azure. New leadership came in. Rewrote it "all" (3 years in so far) into a wait for it, MONOREPO! in Python (at least they used FastAPI), Next.js (just to have a useless API which calls other APIs, because apparently 'cookies are more secure than JWTs' (I guess they think not being able to fetch them in JS is somehow security), and AWS. So far it has half the functionality, 10x the libraries, 100x the confusion, but hey, at least we went from 5 devs to 100 just so everyone can be confused TOGETHER!
