Setup how? I've used vi/vim daily as my main editor for the past 35 years or so, over that time I doubt I've put more than 20 total hours into its setup. I've been using some evolution of the same .vimrc for decades and it's only accumulated a couple dozen lines. The longest setup task I can remember was a few years ago getting MacVim to launch with one window per folder (with files as tabs, in most cases that equates to one window per repo, handy when I'm working across a couple different ones), but that was all shell work, not within vim itself.
