I appreciate the criticism, thanks! I disagree, though, that adhering to standardised formats is not worth it. Currently, there are countless todo apps and editor plugins out there, which all do very similar things. However, each needs their own dedicated editor plugin for syntax highlighting, and you can’t easily switch the client apps without having to also switch the underlying data format.
What I agree with is that standards limit the creative freedom of tool creators. But that’s the same balancing act all over again, no matter where you look at.
