The index is not designed to hold tree objects (at least not at this level), and update-index should be fed only the full path names of files, symbolic links (mode 120000), or gitlinks (mode 160000).

Whether it's reasonable to ask for the update-index command to understand that `040000 tree <treeid> <path>` means to insert all the files *within* the given (existing) tree object, at the implied constructed paths, I'll leave as an open topic here. :-) But if you were to do this manually yourself, it should work.
