Okay, I think I see what you were going for, but I'm still not convinced
that pulling these values out into separate arrays is more clear at the
moment. You still have to make sure your arrays stay in sync and if
there's any control flow (e.g., some properties are only relevant on
certain platforms), then that gets more complicated as well.
I'd suggest not using the arrays for now while we only have a handful of
properties. Once we have a large list of properties in the driver maybe
we can revisit whether there's a nicer way to stick them in a table and
simplify the code.
