You could have an entry file for your dependencies (let's say dependencies.ts) and reexport everything from there. When you have to update, you only have to upgrade it in the entry file and you can avoid multiple versions.

Hm, how about we call that file package.json?

How about we link them to modules downloaded onto local file system instead, just in case of network issues.

How about a cli tool to cache and build those modules/native extensions all at once? We could call that Deno Package Manager.
