One more segment could be for the number of multiple cursors. I've minor-mode lighters disabled in spaceline. So, I've no way of knowing how many multiple cursors I've.
Add a segment to indicate the number of multiple cursors active when multiple cursors are in use, and not being displayed as part of diminished mode.
