That's right -- I left that part undone when I added the ramped tempo feature in 2006, and as far as I know nobody has looked at it since. MIDI doesn't have any way to represent a ramped tempo, so to implement it would, I think, mean having to emit a tempo change at each event, calculated so as to give the correct time gap to the next event. That is, using e.g. Composition::getRealTimeDifference to convert the gap to real time, and then picking the fixed tempo that would result in the musical time gap being converted to the same real time. This is not _hard_ as such, but it is fiddly, and it's worth noting that the exported MIDI files would end up with multiple fixed tempi in them if re-imported, rather than ramped tempi.
