My 2 cents -- Save the depend files. They take up very little disk space, and if you ever want to migrate a specific VAR from one computer to another, it can be a handy extra reference point. Not all assets can be discovered from the Package Manager. If the author of the package does a good job, every required asset (regardless of whether VaM / Package Manager knows its URL) should be included in the file. Personally, after I build a package, I modify/fix the depend file to include additional information to make it more useful. Perhaps most creators don't do that though. IMMV.
