Clear system resource after Removing a system

[eXponenta]

I use a isolated system for Debug drawer, and add/remove it dynamically.
Ok, there are a init method, but how to free resource after removing a system?
I found a mark in sources, but still not implemented.

How to use curent version of ECSY for this case?

Did you solve this problem somehow? A month has passed. The authors are clearly not worth waiting for
