Putting on my flame suit...

The same way you have had to regulate them since they screwed around with 
the backchecks in the mid - late 80's, and the voicing since not long after 
that...that is, with a smaller and smaller range and domain of control and 
usability...which is, of course, just fine, so long as everyone who plays 
the instrument is largely interested in the keys as on/off switches, with 
smaller usable dynamic range and decreased tonal pallette...

not, of course, that I have any opinions on the subject...

Best.

Horace
