But I would like to develop the engine towards embeddability: to single out some simple part from it that could be connected by a library to any Go program. Conventionally, if you already have a microservice for ... what is it good for ... even for rendering 3D scenes, you can embed a bot chat into it in one or two lines for operational diagnostics / monitoring / control ... This, it seems to me, would be useful. In fact, you can do that now. It's just not very convenient.
