Yes, it wouldn't work for Ubuntu. We don't maintain our task data by hand like this; we maintain it automatically using the output of germinate, which expands out dependencies very carefully taking a number of things into account. For example, packages that are explicitly part of "inner" seeds such as the base system are installed preferentially. If you only put the root packages in the task, then you would rely on tasksel expanding out dependencies in the "correct" way. It wouldn't just be able to feed them to apt as some of these situations are very complex, especially when virtual packages are involved and we have to choose which Provides to pick, and apt's dependency resolver doesn't always get these "right" (where "right" is defined as "matching the current behaviour" since we're pretty happy with the current output) without help. Task expansion would no longer be the role of a single program (germinate) but instead would be spread across several wobbly piles of software; the net result would be that Ubuntu's tasks would become more fragile and harder for us to maintain, for no added value to users.
