Yes, there are. And not only in my head, either. :)
I just haven't got around to starting a design doc.

I agree that better designs are possible. Certainly the pseudo-file
approach should be an implementation detail of the wire protocol.
However, I would hesitate to invent actual new node types because they
cannot be represented in older repositories, making the client<->server
compatibility problem harder.

Later in that same IRC log I concluded that talking about symlinks to
the WC makes sense, as they're something most filesystems know about.

That depends on what you call a top-level API; mine for symlinks is
called "ln" :)
