WordPress Twentynineteen css

Thanks for the new Twentynineteen theme guys!

I love wordpress!

Unfortunately it looks like with the new theme 2019 you forgot about that beautiful slogan “code is poetry”. The standard 2019 css is a 200kb mass. Even when reduced by a minifier there is still about 100kb left. Sure, it should be universal. But why did you put the media queries all seperately behind the non-query rules? Is this due to SASS?
