General answers for a general question.
Policy is in the eye of the beholder
The bean counters with proper software can track an engine's performance and remove it just-in-time to save the most money between fuel burn costs, repair costs and out-of-service time.
Since a single surge is not considered a safety detriment, it may be used as a point of information according to the intent of the lowest cost management plan. (note that different requirements for different engines play a roll)
Things that do attract the greater attention are shutdowns, air-turn-backs, diversions and forced removals
Now FADECs are good but they aren't good enough to prevent a surge if you wear out an engine.
And those old nasties that surge in reverse are wearing out engines pretty fast by letting them surge in reverse. (the question there is how many times?)
