To more finely defined gearing ratios, manufactures might try making a finer chain. For example if the chain links were half as short you might be able to ge 22-68 cassette and 104-84-60 chain rings using the same diameter sprockets and chaing rings. With such teeth, you would be able to more finely step the the cassettes. If the rings themselves were thinner, you might beable to fit more sprockets onto a cassette.
Has any manufacture tried to tackle the technical difficulties of this. I am certain that with new space age materials, you should be able to make a finer chain link with equivalent strength.
A chain with a 1/4 pitch would not have rollers or pins large enough to transmit the power for your application. Also the tooth profile would be too small for the load.

This method has been used by certain Kunning Konstructors to get big gears on small wheels. The pioneers in this field were John and Miles Kingsbury, who used 8mm pitch industrial roller chain in the transmissions of their racing pedal cars and early HPV's. Latterly, the Virtual Edge uses a similar sized chain for the final drive to the front wheel.
