Thats irrelevant if the files are stored separately. The issue with being
able to fetch part of a file without fetching the whole was so that a
malicious party could not locate the nodes storing certain material
without that material spreading.
Thats not an issue with the metadata stored separately from the data,
because the location of the metadata is in no way correlated to the
location of the data.
