[pianotech] Chickering's splayed actions...Why?

[Marcel Carey]

The only benefit that I could think of is that the keys are all straight. Keybushings last a long time in these kind of pianos.

I've been wondering about the concept of the splayed grand action for a while.

Why would a manufacturer do this to themselves?  I don't mean this as a pejorative question. Rather, I have to assume manufacturers were chasing after some design goal with this splay, since angled shanks impose 88 different geometries, further (and somewhat excessively) complicating an action's already complicated collection of geometries.
