I remember reading that it was unstable or something, so there's probably not much chance to see it back. Plus it was only for some older Atheros devices, so it would not be useful for many people now. They would have to add support for something newer to make it useful, but the question is what exactly. And since they don't produce any usb wireless adapters themselves, their motivation is probably low.
I had my hopes for Woobm
, which I thought would be regular USB wireless adapter, and others with same chipset could work too. But based on FCC data, I don't think so anymore (it looks like it will be just some wireless to serial device, so really only for management).
