Given that one might expect a major use of a maintained connection to be
retrieval of inlined images, and since the user-agent has to parse the
html document before knowing what images to request, it seems that the
"pipeline" method is less useful (although a second connection, with
multiple requests for various images could be used..)

That strikes me as unnecessary. a maintain-connection capable browser
should be smart enough to know when to give up, but may not be smart
enough to know what to do with a unsolicited response.
