I want to believe you. I just can't bring myself to agree, anymore. Most sites are flat out not optimized, at all. Worse, many of them have instrumentation buckled on to interface with several different analytics tools.
And to be clear, most sites flat out don't need to be optimized. Laying out the content of a single site's page is not something that needs a ton of effort put into it. At least, not a ton in comparison to the power of most machines, nowadays.
This is why, if I open up GMail in the inspector tab, I see upwards of 500+ requests in less than 10 seconds. All to load my inbox, which is almost certainly less than the 5 megs that has been transferred. And I'd assume GMail has to be one of the more optimized sites out there.
Now, to your point, I do think a lot of the discussion around web technologies is akin to low level assembly discussions. The markup and script layout of most sites is optimized for development of the site and the creation of the content far more than it is for display. That we have moved to "webpack" tricks to optimize rendering speaks to that.
