IME IPC uses |static_cast<Enum>(aArg)| in a handful of places in IPC which are unsafe under an adversarial content process, because it could send values that are outside the range of valid values. I didn't spot any codepaths where this is necessarily exploitable, but there are a lot of them, so better safe than sorry :-)
Jim, wasn't sure who the best reviewer for this would be, can you suggest someone?
