The grab-bag format is only in the memory, so you don't have to care
about stability / compatibility there (just keep import and export in
sync). If something works for LO shapes, those can be properly
imported/exported. If the shape is edited, the grab-bag can be emptied.
And finally if a property is not something an LO shape / ODF can handle,
it can stay in grab-bag.

That way you would never have conflicting information in the grab-bag
and in the real document model on export. Would this approach work?
