Do you have any details on that? I tried looking at default packages and containers for each version but those are probably too slimmed down. I assume you mean installed by default when you pick a "desktop install".

Really surprised to see /Debian/ of all things pick Neovim, especially years ago when it was even newer, as a default over Vim and would love to see the discussion around it. It would have been ~v0.2 for Stretch and ~0.3 for Buster, and only a year old during Jesse.
