Where do you draw the line though? It seems like you mostly spend your time writing HTTP servers reading/writing JSON, but is that what everyone else also spends their time doing? You'll end up with a standard library weighing GBs, just because "most developers write HTTP servers", which doesn't sound like a better solution.
I'm willing to stick my head the other way, and say I think the languages today are too large. Instead, they should have a smaller core, and the language designed in a way that you can extend the language via libraries. Basically more languages should be inspired by Lisps and everything should be a library.
