i actually changed that because of this:

Hm, the destructor generates a SIGSEGV and the solution is to avoid calling the destructor? That's evil.
Does the crash also happen without your other changes? If so, this should be kept as-is and fixed properly in another issue. If not you should find the root cause and fix it properly now.

Perhaps auto delayed_plug = node->register_plugin<delayed_node::delayed_node_plugin>(true);?

You should keep the "plugins" option. We don't want to change the behaviour of the executable.
