Basically, the Augmented Diffs comprise exactly that information. They carry for each changed object the geometry information, either directly or by referencing the also in the file contained nodes. From that it should not be too hard to mark affected tiles as dirty. I'd suggest the id-sorted variant with info=yes. It is bigger, but the nodes are required to get the geometry for relations right.
