Yes, because in first versions i changed the default and was criticized for it, because it broke backwards compatibility with existing distros, which even don't enable PCI-Generic for both ARM architectures (and indeed ARM64 support for PCI-Generic is going to be enabled in upstream kernel v4.3 only). To tell the truth i'm too lazy now to look up relevant threads.
