Well, it would make it harder to suppress the magic on arms/armor you craft. Kind of a niche bonus, unless your DM is really in to chained dispel magic on magic gear.
You could make larger +'s sooner, which could be useful but expensive.
I see, are there any magic items with CLs over 20 that you don't need epic arms and armor for?
