`dumppath` wouldn't work because emergency dump uses `get_current_directory()` to create dump path (you can see it in this PR).
JDK-8196050 covers not only emergency dump path and also `maxage` and `maxsize`. We will have to discuss a lot for this RFE, but it does not seem so active. And also I think it can be split - dump path and the others. This PR will help JDK-8196050.
