I'm worried that someone malicious could link to a post that suggests the user runs some benign command. Then, after the post gets popular, they could "accidentally" changes it to a similar but malicious command. Without history, it would be hard to verify that the "accident" happened retroactively.
Another FR for @leaflet.pub: I wish that pasting Markdown-formatted text (e.g. with `backticks`) resulted in the intended formatting being applied inside leaflet. Or, perhaps better, there could be a command inside leaflet to do the transformation.
I like that @leaflet.pub publications are mutable, but I wonder whether the old versions are stored anywhere or viewable. If they are stored, I'd like it if there was a "view previous versions" link with diffs.
