Cos some config and settings must always be tempered.
If you do sudo apt-get update && sudo apt-get upgrade only files on / will be changed or updated.
I would be careful with this idea as a lot of user specific configuration files for installed software are typically sitting in the home directory. If you install another distro and recreate the same user while continuing to use the old home you can run into issues.
I personally run several distros in parallel on my machine. I created a separate data partition that contains all the real data, as opposed to config files (typically hidden files in the home). I then bind mount this data partition to a subdirectory in my home using fstab.
Very robust setup in my experience. That also doesn't require me to trust the installer to not erase my data, because I am telling it to completely ignore the data partition, as opposed to mounting it as the home partition...
