To add a bit of perspective, can you visualize what such ergonomic design
might do for the piano?
The essence of a keyboard is found in the keyswitch -- the plunger and the
contacts.
A good plunger is not lubricated and does not bind even if the key is
struck at an angle. Any external lubricant eventually wears through.
Good contacts do not bounce.
Good contacts do not fail because of oxidation or exposure to common
atmospheric contaminants such as moisture, ammonia, and oil vapour.
Gold is not necessarily the best contact material for very low voltage and
current, because oil vapour can form an insulating film (a polymer, if I
recall correctly) on gold. I think that it was Honeywell which published
a report on this matter. For a quality keyswitch, a wiping silver contact
may be a better choice.
