I understand the concerns. The Content-ID itself is build around the
'multihash' idea, where the string not only contains a checksum, but
also which checksum algorithm was used - to support multiple checksum
algorithms at the same time and also to be compatible with new checksum
algorithms.

The definition of the Content-ID[0].

Behind the Content-ID is a JSON file, which get's fetched from IPFS.
This contains entries of the individual blocks of a file, with a size
and a Content-ID for this block.

So the data-structure is extremely simple and could be used with any
protocol.
