Indeed.  However, this does not create a new weak point.  Your suggestion
does.  Hit-count information can be dropped the very instant the recipient
decides they don't have time to deal with it, and can at the very worst
create an inaccurate picture of document popularity.  This absolutely pales
in comparison to the problems that might arise if a node started spewing
redirects (to either legitimate or non-existent addresses) in response to
every request they saw.

Two round trips instead of one.  Great idea.

IIRC, the goal here was to increase the persistence of popular objects by
making popularity information more accurate.  The Principle of Least Fucking
Around says that changing Freenet's entire caching/routing strategy and
introducing myriad new possibilities of error or attack is not the way to go
about it.
