I think there is some confusion. JOSM uploads nodes first and then
ways. That's just because you cannot create a way between two nodes that
have not yet been created.
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.
I don't think anyone tries to suggest that JOSM first uploads an empty
node and then uploads it again with the tags associated with it.
