Oh no... This thing about deleting GPX traces. I don't like it, we
should never make people delete the files. I think it's blasphemy to
remove data from the traces db.

I also use josm and I do it like this:
1. load GPX file
2. download GPS traces for that area
3. upload GPX file to OSM
4. edit

The traces downloaded from the server are just dots on a map nothing
more. As far as I can remmeber they have no metadata.

You should always create OSM data layers from a GPX file you yourself
have created. Never from traces that is downloaded from the server.
And I'm not quite sure why it's not strictly verboten. Imi?
