Apple’s statement: https://support.apple.com/en-us/149555
I think this is basically related to apple's SIP system protection: they haven't figured out a way to update this quickly and would need to roll this out in like an OS update, which can take a while.
They might need to make a way to do this outside of os updates
Are they just saying "do it yourself"? Can't they just send out an update?
Indeed!
