Agree on that. There is lots of UK data with source=NPE or PGS that
has obviously been subsequently adjusted from Bing or elsewhere,
probably done this myself many times and forgotten to change the
source tag.

That's why I would prefer some automation. If I have Bing and an OS
based layer open and active in JOSM then I don't see a problem with
automatically adding those as sources to the changeset. Those tags
should then be visible when retrieving object history. Mappers could
still override that with source tags on the objects if required.
