VSCodium uses NetCoreDbg. There are community snippets to make the same work for Cursor, NeoVim, etc.
So far, there was little demand to write another debugger integration (because, really, the debugger core is implemented in the runtime itself - what vsdbg, NetCoreDbg and Rider all primarily do is consume the runtime API).
Yes, it is annoying. You can run VS Code on a PI and have an amazing Rust environment, or Zig, or any language. Except for .Net. Why MS? What is the benefit to your business to make .net suck without your closed sourced bits?
Further, the twitter posts themselves are still relevant I believe. If someone took over my repo, I'd remember it 3 years later.
