But that automatically means that if you upload in multiple chunks and something goes wrong after nodes have been uploaded, it can occur that the nodes will be created but the ways not. And since most nodes that belong to ways have no tags, you end up with a bunch of untagged nodes.
This can be solved by splitting the upload into spacial correlated pieces. A really smart unloader would cluster the data into tiles of 1x1km and upload each one individually (nodes & ways in one diff).
Even for huge ways it is possible to upload 150 nodes and a way and then another 150 nodes and a new version of that way covering all 300 nodes.
I remember some garmin map creation software that even creates those tiles based upon the number of objects in it, so that in areas with less data there would be also a decreased number uploads.
