I don' t have a big problem with this, since the change is obviously
harmless if it
doesn't need to be used. But similar to my comment on patch 3/5, is there any
history/technical reasons we can capture here ?

I did a quick search to dig up a bit on this myself, but a summary
would definitely
help, since I see that this has a long and sometimes twisting history. Is it as
simple as ?

 "A machine.conf or local.conf can increase MACHINE_KERNEL_PR to force
 rebuilds for kernel and external modules"

Cheers,

Bruce
