Yes.  They share "having to guess" property because their data
source does not tell them.

You need to find a hole in the existing readers to stick the new
information in a way that do not break existing readers but allow
updated readers to extract that information.  That is exactly what
we did when we added the protocol capability.  I do not offhand
think an equivalent hole exists in the bundle file format.
