If you wanted to you could && a few symlinks and other commands into 1 copy / paste'able command to get up and running really quickly. It's also painless to manage secrets by sourcing in optional files. It also works nicely when you want files living across 2 systems (such as WSL 2 and Windows) where on a Windows box you consider certain Windows files dotfiles even though technically they exist elsewhere.
I've been managing my dotfiles like this for a few years and it seems to be working out well not just for myself but others who have want to use them either partially or in full. I open sourced them here: https://github.com/nickjj/dotfiles
I purposely broke up some of the commands because I know that not everyone will want a 100% replica of my dotfiles. Folks copy / paste only the commands they want.
