An important eeschema use case is a "project specific library", where
you would *copy* a non-part-specific symbol into your own project
specific library, and assign a value to it at that time, along with
datasheet, vendor, footprint, etc.   This could be done for each unique
part on a board.  And no matter how much we try and avoid having to do
this, I suspect it will still need to be done.  Therefore I consider
this something important to be considering when we discuss changes in
the UI and file formats.

> Will the component-library also have a reference to (default) footprint(s)? Related to this, if a component is available with different footprints are they different components, or the same component with a reference to multiple footprints? If the latter is true, then one could easily choose another footprint in newPCB, for instance.
