No it does not, as doing so introduces a very large burden of maintenance work for each change.

Actually we're almost in a position to do  runtime plugin enable/disable now, since we no longer use boot scripts to activate the plugin applications. There is a bit more work to do though, and there is an open ticket to address the gap.

Erlang makes this possible, but there's still a lot of work involved and it is an ongoing maintenance overhead rather than just a one off task. I don't know of any plans to support rolling upgrades in future.
