I didn't put the recommended aluminum sleeve in my Cervelo steerer tube, but just an expander bolt.
Now if some brands say it has a structural support function, I might just glue it in there, just to be safe.
Not me personally, but just the other day a guy brought over a fork where this had happened. I'll see if he's still got it and check to see if the compression plug was too small for the fork.
Also, I have a cervelo P3 and I absolutely expoxied the aluminum sleeve that Cervelo supplied for the fork.
These things often do provide structural support for many carbon steerers. Sometimes even though you loosen the stem bolts, the stem is very difficult to get off until you loosen the compression plug. If the fork is supplied with a compression plug that looks like it might even remotely provide some support or reinforcement to the steertube, I will use it every time.
