All nonsense aside, how about reducing decompression times with heliox
mixtures. Replacing say 32% NITROX with 32% oxygen/68% helium and reducing
decompression times as the result of eliminating Nitrogen in the deco mix.
While helium also gets absorbed by the tissues it also off gases at a higher
rate.
