Bear in mind that there's no such thing as a mechanical 'sealed for life' gearbox - anything that spins in a bath of oil will degrade that oil over time with heat cycles and shear forces on the molecules. No oil ever made will perform with the same efficiency after 100,000 miles as it did when new, it's a simple and unquestionable fact.
So, with this in mind, all our A2 gearboxes will need an oil refresh at some point to keep them in good condition is the answer to your initial question. Whether a mechanic deems it necessary is irrelevant, they could simply have been talking themselves out of a job they didn't want to do for whatever reason. Their experience is of paramount importance in their mind, but hardly exhaustive when it comes to the question of A2 gearboxes, which have been stripped and built, modified and tweeked by many members here, myself included.
Rather than him just do it and cross his fingers, I'd urge you not to have the work done by them, because the chances are, in their experience, something will subsequently go wrong. This gives them a get out clause of "I told you so". I'd recommend you have the work done by someone who knows what the procedure is, what type and amount of oil to use and how to ensure that you don't have issues.
