Improvement: Eagle files for Shield design

This suggestion is valid for all your arduino products (uno, mega, due and so on) which i hope you can consider.

It would be really nice with eagle files containing only basic features required for shields.
Such as headers and silkscreen (top and bottom please)
Hole and feature marks
Dimension

This would make it easier for users to create shields or other adapters without having to worry about placement.

I know it's possible to take the full design (huge thanks for distributing those files) and start deleting stuff but it would be nice with the option to download a simplified version for shield designs.
