This is all nice and fine for the short term in those areas where you are 
filling in a blank map. But over time more and more people will be editing 
existing objects where this simple approach simply won't work.

To give an example:
There is this convention centre where the building is drawn from 
source=whatever_aerial_image. Then they build an extention on the south side. 
So someone changes *part* of the shape of the building from 
source=municipal_planning_office.

Just putting those two sources semicolon separated in a tag isn't telling you 
what happened or what is the source of what.

Source tags are outdated. One of the main arguments for introducing the 
changeset tags was that source tags on objects are not "good" enough.
