After a discussion with George about /o and some background reading and thinking, I have concluded that /o is poisonous, and at high risk of creating bugs.

The main scenario I foresee is where /o has been used on a RE that interpolates a cfg var. cfg vars are supposed to be constant, but there are cases where we need to change them dynamically. Since /o applies the first time the RE is evaluated, it may be a lottery as to a before-change or after-change value is picked up for the interpolated var.

The safest course is to remove all /o's from core code.
