> There should be additional facilities to provide for the case where a transformed configuration
is not valid or leads to issues with restarting.
> One approach might be to cache the last good configuration and attempt a restart, where
if the process failed to work successfully, rollback.
> Another would be to attempt some validation of the resultant flow before killing the
existing item running, but could be difficult given how closely a FlowController is tied to
runtime.
