   I have read the proposal and my understanding is that you are trying to index data form the same source with the same interval of time but you want to break it into more sub tasks to make it parallel is that the main pain point that pushed you to implement this name spacing  ? OR  is it because you have some data reprocessing and you want to re-process only sub part of the data and the only way know / filter this data is what you are calling namespace ? In my opinion for both cases i would agree with the general sentiment that this is better done in the Query layer as standard union and would be a wonderful contribution that can be used by many other use cases.
