Right, its puts some flexibility in hands of a user.

In the messages hitting the TIME_LIMIT_EXCEEDED in our log for the
past month (and examining their rule hits, score, and subject),
I can say that the rule hits which triggered during the first 45 seconds
of processing always yielded a reasonably good approximation of the
expected final score. One would be extremely unlucky if rules that
did trigger contributed a large positive score which would have been
counteracted by a large negative score of one of the rules which were
aborted. While it may theoretically be possible, I think that a mostly
neutral default score for TIME_LIMIT_EXCEEDED is a good approximation.
Assigning it a large negative score would counteract the whole idea
of why this was implemented in the first place (large spam messages
were often given a free pass). I'd like to keep it as it is.
