You'd add size when you include whatever DOM abstraction you wind up going with, but at the same time you wouldn't need to add much else because the Go stdlib is pretty complete. On the other hand JS developers are adding Lodash and other utility things that Go already comes with.

Well these days people are using tree-shaking and ES6 imports to only include the lodash functions they actually need.

My point isn't that Go should be banned from WASM or something, but that "5x increase in library size for zero functionality sounds fine" is a disappointing view to see given how hard the JS community has worked on bundle sizes.
