You can also cause JOSM to upload an unchanged object by modifying a
tag and then later changing it back to its original value. To prevent
that I guess JOSM would have to keep a copy of the original state of
every modified object to check against.
Personally I do it quite often to stop mappaint "painting" a
particular object. For example mappaint colours in areas making it
hard to see traces running through them.
For example I'd change the way tag to landuse=residential# to stop
mappaint colouring it, map some traces, then change the tag back
JOSM will upload the landuse=residential way even though nothing has changed.
