Splitting changesets does sound like a lot of work if you don't already
have for example the multi layer tools that JOSM has.
Would a warning that "you already have pending edits ___ km away, please
consider saving or discarding those before editing here" be useful in the
interim? I think this would "only" need the software to keep track of the
bounding box for current edits and notifying users if the closest point of
the current edits is out of view by quite some distance. This avoids the
need to split pending edits into multiple changesets because the prompt is
shown before work on the second region starts.
