Living in a seismic ares I have certainly seen a vast improvement of the suspension of both the grid and the luminaires installed there as well as a general improvement of the wiring in them. Still a lot of poorly supported wiring of all function but an improvement.
I am seeing more new buildings that just spray everything black rather than build a t-bar cieling. Those cielings often have very good looking installations as it is out for everyone to see.
T bar or the equivalent is here for a long time to come.
