Thomas Mueller commented on OAK-433:
------------------------------------
I'm not strictly against changing the current behavior, but I would like to
better understand how 'bad' the situation is. As far as I see, the only place
where it is stored is within a blob id, which is stored as ":blobId:". That
seems fine to me. Empty strings are also encoded as empty strings, so I think
it's OK if empty blobs are encoded like this. But maybe there are more places
where it might cause confusion?

> Calling {{MicroKernel.write}} with an empty stream as argument, will return
> an empty string as blobId. While this is not strictly a bug and retrieving
> the blob by that identifier works, I think it is confusing and should be
> reconsidered.
