Mark, The 1M increment for RUCSA storage was not chosen haphazardly. We understand the scarcity of below-the-line memory, but in order to provide the isolation needed to adequately protect the area we couldn't use any increment smaller than 1M.
Also, in case anyone is unaware, beginning in z/OS V2R4 RUCSA is a separately ordered paid feature.
