Sugino’s rumored to be working on a prototype for a track hub/cog interface that would allow you to swap out cogs using only a bottom bracket tool. You could leave the archaic chainwhip hanging on the shop wall and dial your rig with a much easier-to-use tool. Not sure why these photos show cogs in anodized blue, unless Sugino ran out of the 3D violet.
