Ok, so it's good we can finally refer to other node types. But I worry about putting all that in a single namespace. The IPLD node types constitute different hashing strategies as I describe above, but stuff like media codecs are orthogonal to hashing strategies---media of various sorts given a hashing strategy will be treated as black-box binary data for the foreseeable future.

The big takeaway here is a really like the idea of IPFS, and want to be a full fan, but everywhere I look I see dubious interfaces. I see what already looks like legacy cruft, and they haven't even hit 1.0!
