Like how they're introducing admonitions syntax by overloading the blockquote sigil that makes it difficult or impossible to nest, has a heavy English bias, and doesn't even transform the underlying element making the use of blockquote unsemantic. They also just skipped the CommonMark RFC and other implementations throwing their weight into the ring with no regard for prior art. I also don't think a corporation, Microsoft, needs to be in charge of the spec either. No thank you.
