Thanks.

I realise this has probably been done to death somewhat; but what do you
think of exposing 'None' as the revision in this case? It would let me
detect when it should not be included in the commit candidates list.

As far as the changes to recorded transitive alterations in inventories,
its not clear to me that that will affect the last_modified flag. It may
well just add another field, or be an emergent aspect of the storage.
