Native support for plugins was added to Vim back in 2016 with the release of version 8's packages. Since then, I've moved from Pathogen in favor of this new feature. Although not a true replacement for existing plugin managers, when combined with Git it accomplishes the same goal. Being a believer in the less-is-more theory, it just seemed like the right thing to do. It has proven to be very easy to maintain and I don't miss Pathogen at all.
