Just to clarify: other parts of the series already fetch all missing blobs that are required for a command. What that bulk-fetch patch does is to make that more efficient, by using a single fetch request to grab all the blobs that are needed for checkout, instead of one fetch per blob. This doesn't change the online access requirement: online access is needed if and only if you don't have the required objects already available locally. For example, if at clone time you specified a sparse checkout pattern and you haven't changed that sparse checkout pattern, then online access is not needed for checkout. > I've also talked about a pre-fetch capability to bulk fetch missing > blobs in advance of some operation.

In particular, something like this seems like a very valuable thing to have when changing the sparse checkout pattern.
