I'm amused (and kinda surprised) to learn that shells have their own equivalent of blink tags, a blink escape code! https://stackoverflow.com/questions/17439482/how-to-make-a-text-blink-in-shell-script Seems equally annoying, I can't see a good use for it.

tree-sitter-elisp now has basic support for syntax highlighting and generating tags! https://github.com/Wilfred/tree-sitter-elisp It works surprisingly well and runs very quickly.

I've seen markdown projects leverage link syntax for custom extensions, e.g. [click me](button://). Markdown also supports embedded HTML. Perhaps you could add custom tags for extensions?
