Node-Delete-Datasets should be a minority, and they will be very small if you get rid of their tags, metadata and lon/lat. For to delete a node you only need its id and - for validation purposes - the version number.

Hi Markus,

I have discovered that planetdiff can generate a change file that
contains the old location and the new location of a moved node, which is
perfect. It can't be passed directly to osmosis but it can be used for
further processing to use changes with a bounding box I think.
