So I'm told. The typical scenario I saw was that the old dead Gulbransen 
spinet had been traded in for a new Yamaha console so little Sally, 
and/or Mom could start lessons. So they segued from a pianoid keyboard 
that offered nearly no resistance anywhere in the stroke to one that 
did, and they didn't understand the difference. I've seen this a dozen 
times at least, and my experience has been that it isn't necessary to 
change the damper spring tension once the problem is explained and the 
student becomes familiar with and used to the piano.
