I build a lot of stuff and forget why I did things the way I did.

You can do things like find the point in history where you fixed a bug and go watch yourself debug and put in the fix.

Pretty wild. It makes a lot more sense once you experience getting the value.

Personally I hope Apple adds the feature natively to the OS at some point. They're plenty experienced to build it themselves over there, but maybe having a reference implementation will encourage them to give it a shot.
