Can't retrieve raw nodes using the dag cli/http api

[achingbrain]

I can add and fetch a CBOR node via the CLI:

$ echo -e "\xa1\x63\x66\x6f\x6f\x63\x62\x61\x72" | ipfs block put --format=cbor
zdpuAspUFE9aaNm5FQB5T3jXig5xDuzRPYGqswYPrZbJHbCqz
$ ipfs dag get zdpuAspUFE9aaNm5FQB5T3jXig5xDuzRPYGqswYPrZbJHbCqz
{"foo":"bar"}

But if I add the same data as a raw node I can't get the data back:

$ echo -e "\xa1\x63\x66\x6f\x6f\x63\x62\x61\x72" | ipfs block put --format=raw
zb2rhe3JxU16E17kG3GSnUW5paVwzNrnpFwLCiQPRbeediA8t
$ ipfs dag get zb2rhe3JxU16E17kG3GSnUW5paVwzNrnpFwLCiQPRbeediA8t
{"Block":{}}

Since it's a raw node I would have expected to to just blurt out the raw data and (potentially) make my console go all weird in the same way as the block api:

$ ipfs block get zb2rhe3JxU16E17kG3GSnUW5paVwzNrnpFwLCiQPRbeediA8t
?cfoocbar

Is this intentional?

No, this is because our current IPLD implementation doesn't currently have a nice way to translate between node types. Quick fix: ipfs/go-merkledag#36. Longer term fix requires https://github.com/ipld/go-ipld-prime.
