Perhaps the two of you can partner up on that.

My point was that something needed to use it. Having a couple extra
hundred lines of code in garmin.c without any formats that can use the
extra data didn't seem like a plan. So turned off the code until someone
was ready to hook it up to something.

That can be handled in extra_data. Data not associated with a position
is not a core concept in GPSBabel becuase it's not a common trait in the
data files we convert or the devices we use. Create trackpoints with
invalid lat/lons if you like. The moment you convert those to any progam
that expects lat lons or try to do math like distance of a path when
some of your trackpoints are at the north pole and life will be bad.
(I'd probably just use the most recent location info which would avoid
some of that wierdness.)

It's not an unsolvable problem.
