(Replying to the entire conversation thread) The way I see it: No data about the objects themselves should be in changeset description - changeset should only describe the *change* itself. Because - at least to me, but I do expect to many others as well - it makes the database structure more clear and intuitive.
Even though source tag is metadata, it's still data about the objects. I sort of agree that metadata doesn't belong on objects. Or maybe it should at least have some header differentiating it from actual data ("meta:source"). But having data about objects stored on changesets is still worse. Source tag does indeed have described problems of specificity ("bing;survey;knowledge" - which is for which tag) - but these are mostly edge cases, and a lot of other things in OSM have very similar problems, and still manage to be very useful in most cases. What needs to be kept in mind is the *usual* cases where the information is useful: when I see a feature on OSM that conflicts with what I would edit there, source tag gives me at least some understanding on which information is more correct. E.g. when correcting a way to match Bing imagery or GPS trail, "source=landsat" is a very different case to "source=survey". Or when changing a name, "source=knowledge" is very different from no source tag at all.
