I sure hope so. the problem with current use of ieee80211_rates is
since it is targeted for ABG rates you can have all rates ready in
advance in the ieee80211_rates vector, but as soon an algorithm will
need to move those rates to siso/mimo, 40 mhz, ect. each combination
will multiple this vector, ending in a very big one. using the flags
will allow any rate scaling algorithm to keep using current
ieee80211_rates vector method, with any flags combination suitable.
