For a long time I have been using the thunderbird stable ppa to ensure I had the most recent stable version. When playing around with some of my enabled ppa repos today I noticed that the thunderbird stable ppa for Lucid no longer contains thunderbird; it is now in the standard repos.

Can someone confirm that this is the case, and that TB is now fully updated using the lucid main repos, just like firefox stable ppa became unnecessary some time ago.
