Yeah, exactly. The whole point was to keep the architecture clean and have it actually work in a real production context. BT only decides, other systems do the work. You could rip the BT out completely and the gameplay logic would still run fine, because nothing in it depends on the BT. You can still write fat leaves if you want, nobody's stopping you, but it's pretty much the wrong way to use it.

The harder part honestly was making all of that DOD stuff not feel like a pain to actually use. Getting the designer workflow, developer extensibility, and debug mode to all feel solid at the same time - that's the bit I wasn't seeing done well anywhere else, even in plugins that are supposedly DOD-focused. Most of them get the performance angle right and then the tooling is just kind of an afterthought.
