Nah, I don't think it will become a trendsetter. The default permission system in Ubuntu is pathetic. Its ok for noobies and emigrants from the windows world. It seems they r making it look more windowish like over the time. I guess the change wud be almost transparent for the noob users neways who r chained to the home directory. But I hope it is not aimed for servers. Hell, we'll have to operate on "/system/config/named.conf" for DNSs instead of simple "etc" ones?? That wud be quite tedious.
