If you do residential service...
Would you respond to a call where the complaint is a lightning strike and the homeowner wants to be sure the wiring is OK? The homeowner is going to pay you and will get approval from the insurance company prior to the start of work.
Also none of the above, but have done so and and will do it when needed, seems to be the right thing to do. Might not be warranted to check 100% of the wiring in the building, but at least starting with the several obviously affected circuits, and finding them all ok can make everyone feel safer.
