The copyright/licensing is important, but it was trying to say more than that to limit the scenarios in which generated code would be contributed. I think determinism in the tool's operation is valuable, but probably not the key point to get across here. We don't want a free for all in hand editting and then contributnig any auto-generated content. We only want generated content included where it was explicitly intended that it serve as a "template" for human refinement. Determinisism in the sense that if a 2nd person used the same tool to auto-generate the base template for editting, they would be starting from the same place as the original contributior. > As a trivial example, this rules out a hacky one-off python > script that produces output by iterating through a hashtable > if you forgot to add a "sort" to that ordering to make it > deterministic. NB it is trying to say that the way the tool operates is determinstic, not that its output is neccessarily stable wrt things like sorting. ie you can rationalize about what the tool is going to emit, but.
