Front derailleurs are dead for mountain biking for good reasons. If Shimano had perfected their shiftable narrow-wide system (and companies had kept designing kinematics around multiple ring sizes) it would be a different story.
For example, the Titan worked awesome with multiple front chainrings but I wouldn’t give up n/w retention for faster/easier swapping between rings.
