you can use it to (sometimes) transplant your personal config and documents onto another OS, but it comes with the tradeoff of losing space in root that might be used for massive libraries (compute libraries suck in this regard).
And sometimes your /home will depend on things that your rootfs doesn’t have, which has caused problems for me before. But if you planned for these things beforehand, and your installed software doesn’t do something really dumb, it can work out pretty well, although my personal experience with this is limited to effectively embedded Linux where this is usually a non-issue.
