I don't think there have been any real differences to argue between the
"implicitly" or "explicitly" approaches, but this does argue for
"explicit".  Otherwise, new URL(blobURL) would have to synchronously read
the associated Blob's metadata (which might be on disk or in another
process), and the result of new URL() would change when a blob URL is
revoked.
