It's a compelling idea, for sure, but it tends to delay a bunch of bigger costs. It _feels_ super productive to use "the right tool for the job", but at scale this ends up being really expensive. You end up with an organization that grows using different toolsets, libraries, build/CI systems, training/onboarding, test harnesses, developer mobility, etc. As things grow, inconsistency and inability to share become extremely difficult problems.
