Well the feature itself knows what values it started with. Every update in
QgsFeature goes though the setAttribute, etc, call, you can just have an
internal dictionary that logs when one of values is changed using those
methods.


features are not tied to layers.  QgsVectorLayer (and it's edit buffer)

That's fine you can still do that on the layer.  I'll write a patch and
show you what I mean.
