magit-todos VS magit-delta

This is not an exact solution you are looking for, but magit-todos displays todos in magit-status buffers. If your repository is huge, this can slow down magit, so I don't know if you would use it.

This is an idea I've been thinking about for a while, since Bufler reached a point of stability, to use structs to define hierarchies that can be filled with objects automatically. It finally came together in my mind and this is the result (still WIP, but it's working well). I expect to use this in Bufler, org-ql, and some other projects. It could be useful as a "backend" for magit-section, ewoc, etc, similar to how magit-todos uses hierarchical magit-sections (taxy would offer a cleaner, more flexible grouping backend).

Take a look at magit-todos, IIRC it works asynchronously.

magit-delta's dev is very responsive, but there's still an outstanding performance issue blocking me from adopting it:

magit-delta does this. I tried it a few years ago myself and ran into some issues. About time I try it again :)

For now I disable this package, but I really miss the magit highlighting. I created github issue, but it has no updates since 3 weeks, so maybe community could found the solution?

You might be interested in Delta and the emacs package magit-delta that uses it. It has this feature and several other as well.
