Interesting idea. I do not (yet) have pdf-1.40 so I can not test this. 
Does it work for "normal" cases? The modes manual says

*last* This mode is set if the last run in a session is taking place. 
Normally this is not known in advance, unless one has asked for an 
additional imposition pass.

which makes be believe that it will not work for normal cases. 
However, how about adding a switch to texexec, say --draft, which 
will run the document in draftmode until no more runs are needed, and 
will then run a final typesetting run without the draftmode. This may 
speed up the execution time for long documents significantly.
