Yup.

Hi,
maybe a little bit. For remote-mappers it's a good hint, if objects
doesn't fit to imagery.

Any thoughts about that?
don't put source tags on objects but on the changeset?
If you are interested what the intended meaning is, you should ask the
contributors who added this, I guess different mappers used this for
different things, google is quite

I see no difference in using source= on objects or changesets except
the visibility for the source

Also source=Google really says nothing that source is Google Maps.

I will point out here that iD has invented a new changeset tag which I find
useful. It automatically records what imagery layers you use while editing
and throws them into an imagery_used=* tag. This removes the need for users
to manually tag source information if they are just tracing imagery. I

need to use different images for various parts due to clouds or even
the common case of supplementing survey data with Bing images.
yes, this is very common, at least in regions
