> effectively zero compile-time, one can achieve significantly tighter iteration cycles across a team

I don’t know what machines do people develop on, but on a fairly old laptop I get practically instantaneous iteration with incremental compiles with Rust, which is one of the slowest compiling languages. I honestly can’t imagine where is this supposed slow compiles in case of something like Java - like sure one can create some monstrosity of a build definition, but if some competent person wrote it it is just as fast as an interpreted language. Hell, it can do hot swapping just fine.
