Examples of modern lua based syntax-highlighting plugin?

Most plugins that contain syntax highlighting are older vimscript puglins. Does anyone have a more modern Lua-based example of a plugin that implements syntax highlighting?

I have a feeling that most of the API calls haven’t been implemented yet (I don’t see an equivalent to syntax) but thought I’d ask around.

I’m using nvim-treesitter for syntax-highlighting for every language though. Isn’t it suitable for you?

I guess nobody is bothered with it as treesitter is the way to go.
