I'm too new to WiFi space to know for sure. My guess is "fullmac" is
"good enough" for most users and was easier (legally? Technically?) to
implement. Power consumption might be different or some other features
implemented in firmware that linux doesn't (yet) support.

Well, so far brcm80211 only supports PCI devices. So we can't use that
today. It will take a fair amount of work to add SDIO support. Just
because of that, I think it makes sense in the short term (next 6-12
months) to keep both around. It won't be the first time linux kernel
had two drivers supporting the same HW and transitioned from a "legacy
driver" to a new one.
