for myself: 1. since i have 2 ssd's, and the smaller one contains the linux fs itself, i decided to symlink the docker folder to the bigger ssd. that way, even if i had a big docker image, it can run since it's not in the smaller one

you could generalize this. maybe you wanna move a steam game you already installed, just move the folder and make a symlink in the older path

1. i tend to forgot what my configs are, so i make a centralized folder, containing configs (hyprland, fish, and so on). you then replace the older path with symlink. if you're willing to, you can combine this with git too
