I feel there has been a long history of adopting things as default too early. With bugs like "vt switching doesn't work", and feature freeze in 2 months, I think it is way too early to declare something ready for default. Certainly ship it, make it available, but don't make it the default. Doing so would just make unwilling testers out Ubuntu users. Let people interested in the software test it, and once there is a trusted level of stability and features, make it the default.
While I understand your concerns, I think there's a balance here to avoid major transitions in the possible LTS-cycle. I'd rather see us take a riskier 13.10 to remove risk for 14.04 than push off that risk. Clearly shipping an unusable 13.10 is not acceptable, but I think setting a goal and evaluating that is a better approach here.
Perhaps what would be most productive is to figure out the bugs that are must fix and a time line that they must be fixed in or where a revert is necessary.
