Right now I am too busy to dive into it, not to mention to reimplement a new standard. Also, I write all my articles on Obsidian which renders LaTeX the same way as TeXstr, if I change, I would need to either write them without proper rendering or rewrite every formula before publishing to Nostr. We would need at least a decent editor that renders the same format as Nostr clients for it to be usable in practice.
