Yes, it is. The original patch had an independent toggle that felt 
redundant to you, and I agree. The watchdog affinity follows the 
timer housekeeping state.

I'll simplify this by removing the custom toggle and making it a 
guaranteed side-effect of the global housekeeping state update. 
This keeps the configuration simple while still achieving the goal 
of keeping the isolated cores completely clean during dynamic changes.
