The jury is still out on whether overall durability (that is, structural failures) are affected or not as the trend seems to be there, but there aren't a lot of data points. Please note that all of the above is based on anecdotal data and self-reports over the internet. It's reliability is suspect, but it is the only data available.

I used to run a set of tires at 51 cold, and never once suffered from center wear or bad wet handling. As for trends, the only ones I have seen it for are tires inflated below some 25 psi cold, as there was a famous incident back in the 90s for firestone tires I believe. So 25 cold I assume would be like 32 hot?
Either way, its obvious some tires perform better at higher pressures then others, and hence better fuel economy, what I want to know is which LRR get the best fuel economy while not sacrificing anything else with high pressure.
