Currently G1 uncommits memory in the Remark pause only. It may be better to uncommit at other places (see JDK-8238686) when heap usage is actually low.
Similar to expansion, G1 could regularly check whether the GCTimeRatio is low enough (e.g. < 1/2 GCTimeRatio) to warrant heap shrinking.
Note that the amount of uncommit should be so that heap resizing activity during further operation is minimal.
