Thanks for the links.
The reason I said “overkill” re JOSM, is that as much as possible, I prefer to use a tool that doesn’t have a busy interface, ie. a bunch of features I will never use. Besides, I prefer native apps instead of Java/QT because of the occasional quirks in the look 'n feel, and the time to load the app.

Launched RouteConverterWindows.exe: The logo is displayed for a few seconds, then it disappears, and… nothing happens. Upgraded to Java 8 Update 144, per instructions, re-ran installer: Same issue.
After trying all those, it looks like JOSM is the only app that fits my needs. Too bad GPX Editor is no longer developped.
