I wouldn't say crippled. The only real benefit to having a 64bit OS is to address more than 4G memory total. Since the rPI3 only has 1G ram . . . I'd say it's a moot point. With that said, I've compiled Nodejs 4.6.2 on both platorms. The rPI3 takes less than half the time to compile rom the same sources, using the same compiler.
