Agraffes in uprights

[Dave Davis]

As long as the agraffe design will still allow a good stike point in the high treble. On some pianos, the agraffe does not allow the hammer to strike close enough to the termination, which can lead to some extra woody noise up there.

As a marketing tool, sure. It looks good listed in the 
brochures with bass string length and soundboard area. The 
piano can then be sold for a price difference greater than the 
cost of agraffe installation, albeit in lesser quantity 
because of the higher price. From a practical standpoint, 
they'll maintain string spacing if the tuning pin field is 
poorly laid out. Kimball comes immediately to mind here. 
Otherwise, I'm not convinced there is a real performance 
benefit to agraffes over the conventional V mound and pressure 
bar.

You?
