I personally think Nintendo has given up on blocking vWii exploits, much like they've given up blocking DS-mode flashcarts... It's not profiting them, so they don't care. Now if by some miracle vWii opens an exploit that brings on Wii U piracy, then by all means I could understand them patching the vWii then, but I wouldn't hold out for anything more than vWii Linux running on all 3 cores.
