This is true, but given that many applications are built using web tech now, this stack is sufficient to fire up a server and make an app available on localhost. I can see a lot of use cases for that, and it's something that wasn't there in UNIX before X Windows. I'd use this for my personal projects that provide a web interface, since I can build once and sync (using Syncthing) the actual binaries between my Android tablet, my Macbook, and my Intel laptop. Niche use case, but very neat!

Except modern HTTP and the whole security stack isn't part of those APIs either.
