I'll make this optional after the approach to optional params in #4477 is reviewed/accepted

No need for arg names in an interface definition

I'm not even sure if we want to keep this method, it seems to me that all of it's use cases are covered by Dag.Put

We should still implement it -- it can call DagAPI.Put() underneath

I've been pondering in #4418 whether we should return a resolved Path in almost any place where we already have it resolved internally anyway. In some cases it saves a ton of additional resolve roundtrips, imagine we use the returned Path to pass it directly into another Core API function.

In addition, this is also useful in the case of functions that modify existing objects, e.g. SetData or AddLink. If I call it with /ipfs/QmFoo/a/b/c, I'd like it to return /ipfs/QmNewHash/a/b/c.

(Regardless of that, Put() should definitely return a Path.)

On the CLI/API, object new takes a template argument which can be unixfs-dir for a directory. We can do this here similarly to the KeyAPI.WithType() option in #4477.

Let's call these variables base instead of root -- the root of /ipfs/QmFoo/a/b would be QmFoo, but the base of this operation is b

This looks super good :) Left a comment or two. I think that's all the object stuff needed for extracting the gateway, thanks!

Should I wrap this into an interface for consistency?

I think it's fine - given that the object API is quasi-frozen (it's the old merkledag/dag-pb structure), it's very unlikely this struct will ever have any functions attached to it.

The default for this should be "unixfs-dir" as in ipfs object new --help

Ah, nevermind, I understand :)

This LGTM 👍 - pretty cool!

Next let's extract coreiface to its own package, so we can get go-ipfs-api going.
