----------------------------------------------------------------
First off I agree that backwards compatibility is very important. However, I
believe this is an exceedingly rare case. In that I find it unlikely that there
are custom components out there which require this behavior. Are we aware of
any custom components exploiting this? It seems like this was a hack put in to
support memory channel. As a developer, I would expect the new behavior as in
the patch.

of any custom components exploiting this? I'd be surprised if there are
components other than MemoryChannel which require this behavior. Since handling
re-configuration is hard, I think the default should be to create a new
instance.

> 1) It's not currently possible to provide your own configuration source
> 2) All sinks/sources/channels are reused, even across re-configurations which
> they are not used
> 3) The flume-ng-node module is very complex and starts many threads which are
> not required. That is there are multiple life cycle supervisors.
