We should remove this postinstall step. Compiling the libraries in the postinstall step is much slower than allowing Angular to automatically do it at build time because when you run ngcc it compiles every library (regardless of if you are actually using it) into every possible format while letting it run at build conservatively compiles only what is needed. Running ngcc on postinstall works out OK for local development because the compiled libraries are cached but it definitely has a negative effect in GitHub Actions and Docker builds.
