I would submit that if the jack rail was causing key travel to stop as 
12 - 20 mm from the front rail cushions, then you'd have one whale of a 
lot of broken jacks. The first time you play a bit hard you the jack 
centers would be so stressed that jacks would easily break there.  I 
mentioned something similiar with the damper wires earlier on...  
Anything like this being responsible for stopping key travel in midair 
as it were would have to be able to handle the stress of hard play as 
well... or parts will break.

Keith is right about one thing tho.... whatever the problem is it will 
be painfully obvious when first noticed.
