I just checked these commands out to update my git knowledge, but when I saw the following in the docs [1][2] I immediately marked these commands as not (yet) worth it to learn since the way these commands work might change.
THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
So that might have something to do with it as well.
Especially if there are stable commands that I already know that have the same functionality.
