Even if you have the data you can't do that stuff any better. The makeup of the training set doesn't really define the behavior in any tractable way. If anything I think it's a distraction and even when it is available people probably pay too much attention to what's in the training data vs actual behavior. Edit to say that I see benefits to having the training data, just that I don't think it's needed to exercise enough freedom to qualify as open source in an analogous way to software. Also to add, training on GPUs is not generally reproducible anyway because of execution order.
