I was converting a project from NuGet and run into this:

Introduced in 4c1ae17, paket.targets don't have a VersionInfo attached.

ok this makes me think of what do we do with the targets.file.
We can't decide if it's outdated. So let's do a different approach and download all files if one is oudated.
