I asked about q35 as the default on qemu-devel, Paolo indicated there are
still some migration issues with AHCI:

So similar to what I suggested elsewhere in this thread, I stuck an option to
change from i440FX to q35 in the 'customize before install' dialog. If q35 is
selected, we display a warning that basically says 'only use this if you know
what you are doing'. That's all upstream now
