This is a far bigger change than you realize.  If a header (the section
that would contain the version information) is added to footprint files,
this will create a major change in the board file format as well.  It
may also complicate the footprint parsing and formatting code.  As of
right now, the code for parsing and formatting footprints in board files
is the same as the footprint library parser and formatter.  That is why
there is no header information in the footprint files.  I would prefer
to take my time and think this through rather than just get something
done to meet a release schedule.
