I think you need to make your argument to the FAA.

But, as I pointed out the suits are the direct equivalence to the yellow face cup that pops out of the overhead when there is an oxygen emergency in an aircraft. There is considerable difference between air travel at 40000 feet and suborbital flights to 93 miles. The passenger oxygen mask is fine for lower altitudes but will not work at 93 miles. And there are one or two instances a year were the face masks pop down in commercial aircraft. You are looking at a much higher frequency of "launches" with suborbital flights than has ever existed before. So quoting Soyuz or STS records is really nonrelevant.

Besides they will be worn as unpressurize suits till needed thus are not a nuisance at all.
