Review Comment:
here we are just adding (presumably new) `progress`-es again and again. What
does this mean in practice? If we are still adding the very same `progress`
object, why does it have to be a map? Hence, I guess `progress` _is_ new every
now and then. So the underlying map grows beyond any limit until streaming
session is finished? What if we have thousands streaming sessions at once?
