My thought on this topic is: design everything so these COULD be supported,
but wait until someone tests/implements this functionality with a driver
and needs support for them.  If I understood Johannes' description of things
correctly, if it was found that a driver could do mcs rates in other channel
widths, it'd be as simple as adding the values to the bitfields and that 
driver testing/implementing that functionality.  

What I guess it's come around to is:

1.  Change the way the current functionality is implemented
2.  Add additional values as it's added. 

What I believe johannes was saying is, during the implementation of 5/10mhz 
channels, disable ht/mcs modes up front, until someone shows/implements it.
