I hear you, but to be clear - you're not using markdown any more. A quick look at the docusaurus website suggests it uses MDX, which explicitly does not support commonmark. MDX documents cannot be rendered with other markdown renderers. And normal markdown text can also be incompatible with mdx. If markdown were actually good enough, you wouldn't be reaching for bespoke extensions to markdown to make it more capable.
