Sure, but I think if you see the size of ad-loaded pages as a size budget or standard for your website you're already on the path towards setting your own bad example.

Sure if your use case for go wasm is ads crap knock yourself out.

That wasn't my point, ads and SPA crap available almost in every "modern" site, are several MB bigger in size than Go runtime on WASM.

Ergo a a WASM Go application will be much smaller than those "modern" sites.

I bet even smaller than GMail and Google Docs.
