How is it surprising to people that zip and XML are in stdlibs for a programming language?

Btw, you should have looked at dotnet for this as well. There is a very good library ( DocumentFormat.OpenXml) that can handle all docx/xlsx/pptx files. And dotnet can ship standalone binaries (though AOT probably won't work).

Many runtimes/languages rely on third party deps for that. Also plenty of devs think the stdlib should be as lean as possible.

Personally, I think there should be a balance. The direct consequence of a barebones stdlib is NPM and having to download hundreds of dependencies for a hello world.

Golang has the golang.org/x packages, which avoids too much stdlib bloat while still providing the niceties of “pre-vetted” packages that don’t pull in a massive dependency tree.

yeah I wish Node had something like that

It does! (well Deno does but you can use them in Node)

support is not uniform though

eg: https://jsr.io/@std/dotenv

Difficult to square the author's surprise with the later comment "I have my fair share of building a Java desktop application and know jpackage and alike very well"

You can't get very far in Java development without working with .jar files (which are zip archives).

First party from Microsoft; feels like it would be the way to go.

That is the source of DocumentFormat.OpenXml, you're talking about the same package, https://github.com/dotnet/Open-XML-SDK#packages

Microsoft are incapable of:

    1. naming things well
    2. keeping those names stable
