These will be supported in the upcoming 2.2 release and so are gated on that version. Direct methods call `objc_send_initialize` if they are class methods that may not have called initialize. This is guarded by checking for the class flag bit that is set on initialisation in the class. This bit now forms part of the ABI, but it's been stable for 30+ years so that's fine as a contract going forwards.
