Really, the project is not in a state of code stability that one with a clear
mind would put his data through _online_ configuration changes. You really
want to debug situations with online config changes that exploded or showed
strange effects afterwards?

Hm, quite a lot of things in software are already solved somewhere. The thing
is you would only trust code of unknown sources and quality if you have some
high pressure on you. Is there some pressure on you to rush into lending code
based on java, python or other script stuff?
I have the strong impression you are pressed to release something in a
timeline and for reasons currently untold.
What is the reason for this rush of features and increasing instability, nfs
with server-based replication and so on. All things that the original project
really never talked about.

You would only do this if you had a clear time limit to reach some goal. If
your goal would be to make a well-defined, stable and long term  GPL project
really nobody would ask questions like these. Not in the GPL part of the
software-engineering world. Your goals look externally defined and not based
on the project itself.
