What I mean by that is that the MCP tasks specification that came out in November was marked as experimental. And so, well, you might shrug and say, well, gosh, those clients and servers, they're all supporting a whole bunch of experimental things. Why not MCP tasks? Well, again, you'll see the answer to that as we move forward. Um the next answer to that question is, well, they're pretty involved. Um there's a lot of complexity in here, and that's what I want to do over the next 20 minutes is teach you some of that complexity.
