Well, if you know the alloc/retain/release/copy rules it is just some diligent 
work to convert ARC to MRC code. Has to be done once and believe me, I have 
done it several times. Wasn't difficult. Then also/still runs on macOS.

But you are right, if ObjC 2.0 was introduced 15 years ago it is only us 
"old-timers" who still know the MRC rules. Although Linux kernel programmers 
should also be familiar with get/put calls for refcounting. And their devm 
mimicks the ARP.
