Can we extract this path into client_instance or module_builder static attribute? Also, it might be nice to have a folder instead of just storing it in root. That way, we could even delete the system_desc when ClientInstance.destroy() is called, leaving less things in memory.

I think we should be very of keeping thing in root, and this adds another opportunity to be more verbose (for example, by calling the folder "system_descriptors"). However, I might be wrong. @mrakitaTT do you have an opinion on this?

Any particular reason why this is not just a plain string?

Why is ClientInstance destructor doing this? Why even do this in the first place? I don't think I have ever seen a string being cleaned up.
