Add in the fact that Nintendo figured out selling annual subscriptions is more profitable than packaging games individually, and Iwata's no longer here to champion his pet projects, and you have the death of Virtual Console as a platform.
Even working out Bank/Home compatibility with a theoretical GBA Online would suck. You're trying to transfer data between two subscription services managed by two different companies and the lapsing of one subscription would kill functionality in the other.
