I did get feedback from a couple of our support engineers. One felt it was of no real benefit as it was just as easy to provide the filename as an argument to the jcmd. The other thought it might be of some benefit, but also had a misunderstanding of how the jcmd currently works (thought that with no filename given, it would automatically dump into the current directory). There were no strong arguments for this PR, especially that overcome all the issues it creates.
