This is always the argument but obsidian does a lot on top of these md files. NASA's mission control software stores data in JSON, it's an open format so I guess the NASA software is easily replaceable huh? If obsidian was such a thin layer then why isn't there a good open source alternative? People build their workflows on top of the obsidian functionality, not just the md data.

What do they do besides the frontmatter (which is fairly trivial to process or ignore in a hypothetical future where one wants to stop using obsidian)?
