Direct and to the point. The original intent was to allow for asymmetric
isolation (e.g. offloading RCU callbacks while keeping specific timers
local for very specialized real-time monitoring).

However, I agree that for 99% of use cases, this is unnecessary
complexity. In V13, I will consolidate these independent enum types
into a unified housekeeping mask to simplify the configuration and
reduce the "insane configuration space" you mentioned earlier.
