I completely agree with this view.

However, we have to keep in mind that some particular data models
are concerned with  "data provenance",  and that keeping metadata,
specially "VO provenance metadata", should be something messaging
protocols should be able to do.

ps. I'm using "data provenance" in an ambiguous way, meaning both
"data source" provenance and instrumental provenance.  The latter
is probably  kept in the  binary data,  so sending messages  with
such datasets  trivially  keeps it,  while the  data source  of a
data providing message should be kept around maybe as a parameter
for all rows of the message, or a property of the message.
