Checking it every oil change allows you to clean off the fill plug magnet. If something starts to go wrong you'll hear it and see shavings on that plug. I'd definately want any and all shavings out of my differential, maybe that's why my seals don't leak. Its not that hard to check. Why not at least check the level and overall condition every oil change. I check every fluid during an oil change for level and appearance as well as checking the brake pads, greasing the zerk fittings and checking for any excessive movement in the suspension and potential leaks. Its just good practice, why not take the extra 10minutes? Could mean the difference between needing new pads and needing a complete brake job, could mean the difference between a high speed turn and a broken lca ball joint. I like the peace of mind.
