This is not that accurate if we talk about libraries. Those mostly have well defined scope, well defined interface, and are designed to be integrated so most definitelly feel like LEGO. However, this is totally accurate when reusing the code from your previous project on your next one. I developed many large gov services, and each one reused bunch of stuff from previous ones like user management, complete areas of functionality etc. Here, the analogy is adequate, artefacts from previous projects creeep in constantly. This feels more like single project evolving (or devolving) over long period of time (years to decade).
