Depends on the target audience.  I'd expect users don't care much,
developers probably do.

Yes, most of my virtual machines have a serial console too, even if they
boot into graphic mode.  If I screwed up graphics with a bad virtio-gpu
patch it is very useful to have serial console to figure what exactly
broke ...

Good idea!
