Re "too many things", understandable.

Re "change bus relation", my take is to limit the scope. If the relation is broken before we touch it, then we only need to ensure the part that we are editing (the segments at the roundabout) is not broken. We can have the generosity to also fix the entire relation (re "might as well") but again that's not a hard requirement.

We have our own circumstances, but the team-aspect issue with "confirm but no action" is that e.g. I cannot decide the following:

- you really forgot, and I can/should do it
- you are already cooking at JOSM, so I should stay away and do another note
