Developers are scarce, users are plentiful, so there is basically not a
shortage of people drawing over backgrounds (be it imagery or gpx
tracks) on the other hand there's not many people with the resources to
program this.
Especially since some GPX errors are not easily spotted by an automated
process, and if you need too many traces it's actually cheaper in human
time to draw by hand instead of collecting many tracks so you can
auto-average them.

You might want to take a look at osmtrackfilter, although I'm not sure
it's 0.5 ready yet.
