In concert band, we pick music we feel is best for our band. If we play it well, you are rewarded. If you go to honor band, you are judged on how well you play the pieces you submitted for the contest, not if yoi have a soloist or if you have woodwind exposure ect.
I feel on the marching side of things we do not have the same control of our choice of music. It must meet certain criteria, otherwise you are penalized in your scores at the area level.
If both bands are equal I can see where a soloist or woodwind exposure could help your score but if a band is better without that and can beat a band that has a solist or woodwind exposure why should they not get to state?
If we are not dictating this on the concert side, why should we dictate this on the marching side?
How many concert contests have you been to that bands doing woodwind exposure or soloists?
