How can adding an extra dimension not add significantly to the size?
The only way it won't add significantly to the size is if people don't
use it very much, in which case why bother.
For the record I think this is completely outside the scope of OSM and
should not be done.
My personal interest is only in adding a missing piece of data ... when a road
appeared ... so we can see the development of the motorway system, and other
major routes, or more usefully you can see towns build over time. There WILL be
old routes that disappear or are re-routed, I can think of half dozen changes to
roads locally, but historic ways that have been overlaid with a new road
structure are not very common. The IMPORTANT thing to note here, however, is
that the raods that have disappeared my well be the locations that ancestors
were born or lived at, and that is material that would be useful to be able to
trace!
As I have already said, simply adding a starT_date to a way is all that is
needed for probably 99% of historic mapping ....
