C# has its own share of warts when it comes to AOT -- it doesn't yet support OpenBSD; it does not yet support all reflection oriented keywords; it requires significant changes to msbuild to work with in a standalone context.
But this article reads like someone with minimal background in software went on a LLM prompted delusion and lacks an understanding of the C# language architecture, associated build system, and philosophy. Additions of keywords like the proposed "overspace" attempting to shoe-horn both inappropriate approaches and ideas are a plague on the community.
