To make the whole cycle of data production in OpenStreetMap community
to take advantage of the extension, I think many redesigns in
server-side and client-side are needed.
and I don't think a temporary ID for simplified object is a good
practice because it brings extra work to maintain the relationship
between the IDs of un-simplified and simplified objects. A flag for
the object to indicate whether it is been simplified is simpler.
