I'm not quite sure what counts as a "bogus point" or how you would
identify one - gpsbabel can do filtering based on DOP if you want to
get rid of points where there was accurate fix, but in my experience
it isn't that helpful.

So you could upload gpsbabel filtered traces if you wanted.

You can get josm to join up the GPS points if you want. I'm not sure
if it draw arrows or lines though, as it isn't a feature I ever use.

An interesting idea. I look forward to somebody providing a path to
implement it ;-)

GPS data is already downloaded in a separate layer, and I imagine that
if GPS waypoints were supported they would also be in a separate layer.
