New releases, especially LTS ones, generate lots of questions regarding the upgrade process.
Upgrade path doesn't open immediately after a release. For non-LTS releases, it's opened in a few days. For LTS to LTS, it's opened in three months.
Before it's opened, the upgrade path is not recommended, not tested enough, and can cause all sorts of trouble.
do-release-upgrade -d are asking why they get a "development release" message, etc.
These questions will become obsolete as soon as an upgrade path is sorted out.
I think this kind of upgrade questions should be treated the same way as questions about unreleased Ubuntu versions for exactly the same reason.
