I believe there are a large number of feature requests on Lemmy’s GitHub page, making it difficult for developers to prioritize what’s truly important to users.

Github issues are annoying that way. You could solve it by closing down “issues” and using discussions instead. People can up and downvote discussions, and you can see that from the listview, unlike with issues.

And you can have threaded conversations in discussions.

There’s a user made OpenAPI spec: https://github.com/MV-GH/lemmy_openapi_spec - You probably mean that one

I’ve had similar issues as you mentioned that the dev did fix - but yea, Typescript has less precision than Rust (the source) or the openapi spec. And the Typescript client is build for Lemmy-JS and not build an example for other language client libraries…

Though the OpenAPI Documents in C# and Java are based on reflection of the source itself, and Rust doesn’t have Reflection like that… So it’s probably difficult for them to add without manually maintaining the OpenAPI specs
