"Finally realized"??!  They've known it very well for two centuries. 
Even Steinways have known it, and surely on older Ds they had a 4" or 
5" maple undercarriage on the keys to strengthen them and provide a 
hard balance hole, didn't they?  What I think you mean is that they 
have realized their penny-pinching in the past is giving them hassle 
or bad feedback or something. PR is far more important than quality.

And what's wrong with animal glue for the bushings?  It worked 
perfectly well for 150 years and it works well now.  I've rebushed a 
set of keys today with it.  What are you going to do to stop me, and 
why?
