I don't think there is anything in the spec preventing you from doing
this right now. The fact that only files in the same folder can be
selected is a limitation in the implementation, not a limitation in
the spec.

The spec does require that only the leaf name, without any paths, are
submitted. Is that a problem?

I guess I'd be ok with changing the spec to allow more of the path to
be exposed. However that would mean that there is a mismatch between
what name is submitted and what name you'd get from
