After a few discussions with folks in the lab we've decided that we don't see a ton of
value in supporting anything other than 3990 at the moment. Anything else would be older
(3380) and/or rare to see in the wild (and very difficult to test). As for emulated setups
like z/VM, a user can just use 3390 instead of FBA. So I recommend we move forward with
3390/3990 support for now. We can always add in others types if/when we need them.
