Nice project

but I think the hardest part would be to refactor url references, an url 
might be used in thousands of PickleProperties etc.

I don't know whether image urls keep serving after deleting a blob, however 
If I were to refactor any data, I would keep the old blobs for simplicity

If the storage costs are extreme, so would be the refactoring costs, in 
that case it might be logical to keep the old blobstore logic for actions 
that need editing, and after a blob/image is edited just save it to the gcs 
instead

depending on the use case, switching to gcs without refactoring also seems 
logical, assuming old blobs/urls will indefinitely keep serving

I will not switch to GCS for my old/relatively big app
