Two key things we may wish to implement:

building references on-the-fly, such that the first access to a dataset is slow, but then subsequent accesses use a cached references index; but the user call doesn't change
merging fetches when contiguous: since we know the full set of start-end offsets we are about to launch for each given URL, we could reduce the number of calls to the remote API and potentially save time.

The second point here is complete and implemented in the fsspec backend.

The first has some POC, e.g. nsidc/earthaccess#278
