ack. Up to now, I _never_ had this situation in real projects. Some aspect
of the schematic beyond footprints and packages always needs to be changed.
On the other hand: Almost all projects need debugging and/or service. For
this task, footprints printed on the schematic help to locate the part in 
the layout.

If this is your preferred way to work, you can already do it, even with
heavy symbols: Just ignore the footprint attribute while placing symbols.
Use gattrib, a text editor or a script to replace dummy values of the 
footprints in a separate step.
The mere fact that the footprint information is contained in the schematic
does not imply, you have to set it during schematic capture.
