I understand the idea that gzip should do the heavy lifting of compressing js files.
However the end result is still kind of "too heavy":

• concatenated bundle: > 500ko
• uglified and gzipped: 73ko
• uglified and brotli: 61ko
• swc+minify and gzipped: 130ko
• swc+minify and brotli: 100ko

I suppose it's not a high priority to improve on this, hence the request ;)
