Sorry, for sending HTML as well - I am writing from my phone...
Yes, you will break something, when renaming.
Since order isn't changed, most probably old programs will still compile with old enum.h.
If we want to move from optionOnOff to bool, we will also break old progs.
Since driver is new (mainline for just something like 2 monthes) and stil under devel, I think we should "risk" it.
