Bridge agraffes have been discussed long and often on 
Pianotech for years, and a lot of us think they are a good 
idea. While I seriously doubt they are or ever will be as 
cheap to produce as conventional notching and pinning 
(agraffes need to be positioned and secured, requiring 
materials and labor beyond the cost of just producing the 
agraffe), they do present a more secure and climate tolerant 
alternative to conventional pinning in solid hardwood caps. 
They also provide considerable added mass over conventional 
pinning, which is the primary reason for that increased 
sustain everyone mentions. Until such things become available 
for rebuilders, some of us are realizing benefits in that 
direction with laminated bridge caps and mass loading bridges.
