I generally am very willing to trade compile-time speed for safety or runtime speed. One case I can think of where I wouldn't though is experimentation, where I need to experiment with a built artifact. For example, sometimes I want to run code in a dev environment to test it without building and running an entire microservice graph, and there I feel Scala's slow compiletime rather acutely (even when skipping other steps like checkstyele, unit tests, and integration tests).
