Of course -

...but we chose not to release a front locker due to customer pleaseability issues ("crabbing" at low speeds) and durability concerns, because the front diff is slightly smaller than the rear diff.

We did have some factory released front lockers for some other models in later years, like H3, and air lockers are available in the aftermarket for pretty much everything.

But just because it can be done doesn't mean the factory should do it (to flip your phrase around - lol). The constraints of warranty cost and production volume tend to make OE manufacturers a bit more conservative. We used to have a saying: "...at Chevy, you don't make one mistake; you make a million of 'em".

To answer the original the original question more directly - no. The G80 option gets you a "non-open" diff in the rear, only. Front axle was not affected.
