Not really. The reasons given is that it's not information that should have ever been there in the first place. Again, if you want a system monitor then use something that is designed for monitoring systems.
The decision has really nothing to do with security. All of that metric information is going to be removed from the web interface in it's entirety so take this as a nudge to change your workflow now before the feature is completely removed.
Edit:
To add some more clarity. Our web interface shows you a snapshot of what is happening at that exact moment, you have to refresh to see new information and there is no history kept. Transient issues would never be seen and you wouldn't really ever know the true health of the server. Contrast that with RPIMonitor that uses RRDs to store all kinds of information about the health and status of the server. RPM does a vastly better job at monitoring so I feel that you should use the better tool and not one that is kind of accurate, maybe, if you're running on a platform that exposes the data.
