I don't think that's a good idea... Like me, I know a bunch
of users who
do actually make use of the other VTs, making the default graphics VT
VT1 seems like a good idea, but be done with the six text VTs doesn't,
IMO look like such a good idea.
Remember that this change is proposed for an experimental desktop
specific spin. It doesn't seem unreasonable to me to target users who
don't use multiple VTs.
Keep in mind this is just configuration / default policy. If you want
to try the experimental desktop spin, but would rather have more VTs,
you can change /etc/inittab after the system is installed.
On the other hand, you can also just use the normal Fedora spin, since
we aren't talking about changing it.
