I don't agree. There is an important difference between fixing a
performance regression and making a performance improvement. If a change
made in 8.0 resulted in a significant, unintentional performance
regression, I think there would be grounds for fixing it (assuming the
fix was fairly noninvasive). The aggregate patch addresses a problem
that has existed for a long time (7.4 at the least); I don't see the
need to delay 8.0 to fix it.
