I think it may be quite useful functionality anyway, to check the existence
of a key.
This is what I'm using it for to avoid loading big objects from leveldb.
Can you confirm if that operation does not read data from the backend or is
there any other better way to check existence of the key?

That's what I ended up doing although it's not convenient to have two bucket
instances configured differently to access data in one way or another i.e.
writing through DomainBucket, checking keys through regular bucket.
