Review Comment:
1. I can take it up in a follow-up diff.
2. I started the implementation by using `StatMap` but it would involve a
lot of complex changes to TSE, with changes to each TimeSeries operator as well
as the `getNextBlock()`. It is more intuitive to mimic SSE for the stats flow,
since TSE itself follows after SSE.
