As time goes on and the snowpack gets deeper, it will become more stable. The older deeper layers of weak snow will continue to slowly gain strength. The snow above those weak layers will create a stronger "bridge" making it harder to break into the older weak layers.
The trick is knowing when those old weak layers are completely stable. This is very difficult to determine with faceted snow. It will often fail long after you think things are stable. You might get onto 19 slopes without triggering anything then the 20th decides to release. Or your buddy hits a slope and it stays in place but you hit a slightly different line and it releases.
I continue to hold my cards tight by avoiding the steepest terrain still.
