Maybe one already has a heap of Java code and the latency-sensitive part is only a tiny fraction where optimization will be focused.
Whereas 90% of the time might be spent in 10% of the code image, no 10% chunk of the image can ever be found that contributes to 90% of its bloat.
1% of the image contributes 1% to the bloat, 10% to 10% and so on.
