It's a good thought and in an ideal world with enough resources, I think this is how things should go. But if there aren't enough resources, I think a "JIT" approach is sound where students learn how a browser works as their learning HTML or they learn how the internet works when they're making a call to an API, etc.
They could learn the basics of HTML, CSS and javascript when covering browsers. But to me it is equally important to understand why https and certificates matter, how email works, what's a DNS, a router, what's the difference between an IP and a Port, between RAM and ROM, CPU and GPU.
And even very basic skills like using Excel, Word and Powerpoint.
Programming to me is an advanced topic in computer literacy.
