Fine.  Thanks.  I can add this.

We don't have any intent.  So long as it gets merged who cares how it
happens?

All of this scripting could be done on your end.  No matter how many
dozens of people you educate to add a different prefix it's always
going to be less reliable than just scripting it on your side.

Anyway, here is the relevant bit from my script.  The other subsystem
that requires these is BPF but I only send bug reports for BPF issues.
You also need to do a git fetch of all the trees with subsystem rules.
