Hot reload would still be an improvement on top of fast compile time, but yeah, the most important part is the compile/link part of the iteration. Saving/reloading state could be done at the framework level, and it can't work in all cases (typically when memory layout is changed between iterations). But I think that we collectively realized how slow compilers had become only recently (something like five years ago) because it was a slow boil frog situation.
