Review comment:
So the only reason is to circumvent the behavior of adding "event" to
the `kwargs` which ruins the logic for an operator that just implements the
standard `execute` signature.
It makes it possible to use `pre_execute` as a general mechanism (or
workaround) for adding logic before an operator runs – that's at least my
example use-case here, delaying any odd operator without making a change.
