I think the major hurdle is that they can't just rebrand the existing app, they have to release a new one. Keeping the K-9 app around will help the user transition long term. The folks in this thread follow Thunderbird and Thunderbird for Android development but my guess is the majority of K-9 users don't. At some point when or if K-9 installs drop they will probably revisit the issue.
