My assumption has been there's always fresh air actively added continuously at a rate that can compensate for such small leaks, and that it's just an automatically regulated thing. Maybe a gauge/alarm visible to the pilots would indicate an out of spec level of fresh air entering to maintain pressure, without actually being a "depressurization event"...
But a door-sized hole is a whole (har har) different story.

I suspect that's only an issue on airliners when the hole happens in a window.
There's no shortage of search results confirming that something like gunfire on an airliner likely won't depressurize the plane unless it hits a window....
I suppose if the small hole had existed since before takeoff, you could avoid catastrophic damage as the aircraft will not be pressurized at all. I wouldn't call it a depressurization event, though.
