Answering the first question, no it's not an indulgence. Very few (if any) return to Ali booms after carbon.
In regards to the carbon/plastic corrosion - it aint possible due to fact that there is an absence of an electrolyte.
What is possible however is that the pins that are mounted inside the plastic mould could be of low grade (C.R.A.P.) stainless. I have had problems with a double pin type clip that if left in the open position when storing (clip is in tension) then salt water can get inside and rust the pin - 1 yr and it breaks as the rust expands & cracks the plastic. Best option is to give it a rinse with the hose & clip it closed. Hope this helps.

Big Al,
You might be interested in reading this recent thread - it may change your thinking (re: metal to carbon electrolytic reactions - definitely not plastic though).

.............I've had an AERON monocoque boom for three years ...................
I can't justify the extra expense even if I may get a little more power/planning ability.
Sailing 3km offshore by myself late one afternoon some years ago now, my brand new (used 10times) ali boom snapped at the head (fatigued at where the double tube transitioned to single tube up near the head) and left me floundering in near darkness. Ended up swapping boom around in water but since then swore I'd invest in carbon only. Never had another boom break although have bent the plastic heads of a few having some high speed get offs.
One negative is they're hard as rock when you get smashed into them.
