	`Range` can be used for requesting specific byte range of UnixFS files and raw
	blocks.

Should we be supporting range requests for identity blocks as well?

ipfs-unixfs-exporter has support for these: https://github.com/search?q=repo%3Aipfs%2Fjs-ipfs-unixfs%20path%3Apackages%2Fipfs-unixfs-exporter%20validateOffsetAndLength&type=code

Good question. An inlined block, once "deserialized from identity Multihash" is a valid UnixFS file (it can be dag-pb or raw), so I think the spec covers them.

Good that we support them, (very useful for tests and health-checks), but also unlikely anyone will request range of such small data in real world :)
