Talking purely for myself, I've certainly bought the rtl8192du device
because of its 5 GHz support, as I've made it a fairly hard policy for
me not to buy 2.4 GHz only devices anymore. But this doesn't mean that
a mainline driver only supporting 2.4 GHz for the time being would not be
appreciated dearly, given that the current state of the device is pretty 
much being a doorstop[1] - especially considering that 5 GHz support 
might even become a possibility at a later time, when 802.11ac devices 
start demanding most of the functionality for potentially more common 
newer chipset generations.

So even with my current personal policy of only buying 5 GHz capable 
devices, in practice you probably won't find 5 GHz only AP installations
(aside from long range/ outdoor point-to-point connections), be it 
because of the plethora of existing 2.4 GHz only devices or just because 
of the longer indoor (walls) range of the 2.4 GHz band. In practice, by 
far most of my existing wireless devices don't support 5 GHz (the router
does, of course) because of the reasons mentioned above, but replacing
older devices takes its time.

[1]	yes, I know about https://github.com/lwfinger/rtl8192du/ and
	even have a couple of clean-up patches pending[2] for the 
	kernel-version branch, but those need some further testing.
