Often I do because that's what CI does. This is pretty normal.

But the point is having a different view of what compilation means in the developer's workflow as a language designer. Having the engineer have to think about how to organize the code for the compiler is bad design unless that organization is built into the compiler. The compiler should reject programs that are not organized for optimal compilation. And the organization required at least does not impede understanding of the code (best if it improves it). This is Go's design imprimatur and it's critically important to the success of Go.

FWIW, I see large Java projects compile small changes take minutes to compile, even using hot-reload tools.

Figwheel in Clojure is not like this, however: they're doing something right there.
