Are you saying that we should *require* different images for driver
and executor, as is the case today, or that we should *allow*
different images, but default to the same, as I'm proposing?

I see zero reason to require different images. While it's true that
the driver may need more libraries than the executor, 99% of the time
it's ok to just have those libraries everywhere - it makes
configuration easier and doesn't do any harm.
