For areas where there aren't that many roads and you are at first
travelling great distances it's quite handy to have a gpx to osm convert
function, because tracing some hundred miles from gpx track *is* tedious.
So in my experience the only way to sensibly use the gpx->OSM way
feature is to
a) preprocess the GPX (remove stops, remove obvious junk, basically
keeping only the stretch of road you're really interested in)
b) convert to OSM Way
c) *simplify* the way in JOSM before uploading.

So there's some use case, but note that even with the direct conversion
there's considerable user intervention necessary to get good mapping out
of it.
