in their pipeline configuration
context: D3976 for some DVCS loaders now send one object at a time to the
storage.
So this will allow batching calls to the *_missing endpoints (for dvcs loaders
e.g. git loader).
This slighly impacts the package loaders but this should tend towards null.
Prior to this we filtered unknown objects and kept a buffer of those unknown
objects to flush to the storage given a threshold hit.
Now, we will buffer all objects and then filter on said buffer of objects. So
we may increase calls to the *_missing endpoints.
