It might be worthwhile to balance these positive claims against the language's own stated limitations [1].
Also, I took a closer look at the actual benchmark results [2]. For memory usage, at least, the median would show Goose using slightly more memory than the well optimized C++ and Rust. It looks like the mean is skewed in Goose's favor by a couple of benchmarks where it does extremely well due to its variable-length enums.
