To be able to see available new versions of your dependencies. Good example on how it can be handled is Rust "crates" plugin:

This is "crates", an extension for crates.io dependencies. Aims helping developers to manage dependencies while using Cargo.toml.
Features:
- Displays the latest version of the crate next to it
- Shows all versions (clickable) on tooltip of the crate hovered.
Would be nice to have the similar feature in this vim plugin as well, when opening opam file.
