Incremental compilation results are subjective. If you just changed the file with "main" in it and there was nothing else in there, I'd expect it to be faster than changing a file at the bottom of the dependency tree as you then have to recompile a lot more. Perhaps they're changing some fundamentals of the codebase and (unsurprisingly) the compiler seems slower than you might expect.
