The self-modification-without-restart point is underrated. The current model where you have to restart an agent to change its behavior creates an implicit coupling between the agent lifecycle and its configuration. When the session restarts, you lose working context. Mog sidesteps this cleanly with dlopen-style dynamic loading. The capability propagation design also addresses something I have not seen well-solved elsewhere: agent-written code that inherits the agent session permissions rather than getting a fresh capability set. That is the right primitive for safe self-extension.
