I thought the solution to big files was to use pasteboard promises... not to
setup a pasteboard which is conflicted about what item it is trying to store.
At least that's what I find documented by Apple.

Yeah. Copying a 20MB image to the pasteboard would be what the user wants. Or
better one Gig of video. I think not.
You think like a user (who would assume that the file is really on the
pasteboard) and not like a developer (who should know that the pasteboard
content has to be lightweight).

The TIFF is a preview. The URL is the meat.

That depends only on the pasteboard provider. There is no strict rule. The
provider does not know the recipient and therefore puts everything on the
pasteboard that will satisfy the task the provider offers.
