rawData can be fetched either from the command request or from the operation context. Currently they are guaranteed to always be in sync with one another, but in the future this may not necessarily be the case. And making it available from the operation context is unfortunately necessary at the moment so that we can ensure it always gets propagated on egress, at least until there's a more cohesive story around generic command arguments. So, we should make sure to always check rawData from the operation context.
