  Sure, that makes sense.

  In v4, that kind of patch is no longer necessary.  You can (today!) create a sub-request, and then control which attributes are copied to it.

  e.g.

	subrequest {
		update request {
			... copy the attributes you need ...
		}
		rest
		update {
			&parent.reply: += &reply:
		}
	}

  A little more complex in Unlang, but much clearer IMHO.
