- generating defaults
- overriding defaults with user args
The default generation has been shuffled around some, in order to
make sure that any changes to a specific arg happen in one place
to make it easier to reason about those args. Related args have
been moved close to one another.
The deviceArgs and driveArgs were overly complex after several
layers of copy/paste modifications. Careful pruning reduced the
layers of logic and repeated code, to help make it easier to reason
about.
