GPX etiquitte

I’m fixin’ to do some trail traces in an area I’ve never been before. I brought up the current osm map and saw that someone has already done it. However, looks like they just imported the gpx file and converted it to a trail without any cleanup. There are long straight paths that defy topo logic and likely are the result of gps connecting discontinuous segments. What is the etiquitte for correcting someone else’s work? I’d like correct info in the map, but don’t want to offend anyone.

There is no problem to change other work if you are sure that there are errors in the current work.

OK. I’ll just upload my gpx file and adjust areas where I thing there are errors.
