I doubt Kicad will ever ship with a large set of manufacturer specific
component libraries. I think the main goal is to provide a quality set of
generic libraries and hope that as users create more complete component
libraries that they make them freely available for others use and/or modify.
Once these libraries mature, they could be added to the list of libraries
included with Kicad. As for symbol only libraries, I'm not sure we will need
them if we provide copy/paste into the component library editor.
> 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.
I don't see any reason why the footprint field could not used to define wild
cards for pattern matching or multiple footprints when creating generic
components such as 7400 or RESISTOR similar to what we have already. You could
just as easily create manufacture specific component using the full part number
as the value field which would be tied to a specific footprint.

Generally speaking you should reply to the list. I only email someone directly
regarding a matter that does not require input from all the Kicad developers.
