Another set of ID's that are currently 32bit *internally* but that doesn't
mean they will always be 32 bit.

And that last one (apart from "slave" being obfuscated)

I had "slave" in there.  It got objected to.  See
Documentation/process/coding-style.rst section 4.

is simply incorrect.  It has nothing to do with cloning.  It's the "ID of
the closest peer group in the propagation chain that has a representative
mount in the current root".

You appear to be in disagreement with others that I've asked.

Read the code.

Thanks,
