The reason why is the same reason why any feature is lacking in any product — no one has implemented it yet.

I would guess that on_update is less commonly needed than on_delete, because of the popularity of using auto-increment id's as primary keys, which most often have no need to be updated. So the feature of on_update was not implemented.

There are a couple of feature requests in the Django tracker about this:

I don't know if the patch was integrated into any Django release. I'll leave that to you to research, or ask on a support forum.
