- full_closure is obsolete since it is the same as calling requested_closure with the full list of generators.
- minimal_closure is obsolete as well. Since the recent addition of dependents to the closure via 3d2127ce1e it is essentially the same as the all_missing_closure
Even for the minimal closure case (when a specific generator was picked), we should still force regeneration of all dependents, as otherwise we risk keeping outdated dependents from previous generations
Compute the whole closure of to-be-executed generators upfront before executing anything
Properly compute closures for the 4 different scenarios:
1. full_closure: run all generators for a selected machine in topological order
2. all_missing_closure: run just the missing generators including their dependents
3. requested_closure: run only a selected list of generators including their missing dependencies and their dependents
4. minimal_closure: Run just enough to ensure that the list of selected generators are in a consistent state. Don't execute anything if nothing is missing.
