2009 and 2015 are also not reusable - because of the presence of the Doctor. The last few junctions of the 2009 one on New Years Day 2010 used the news version, because the Tenth Doctor had just "died". 2015's, the Sprout Boy one, has Peter Capaldi's version in the main animation. And since he'll also "die", on Christmas Day this time...
2008's probably shouldn't be reused either - it featured Wallace and Gromit.
The Strictly ident shows that the regular circles being gone is no reason for past idents not to be reused. Any of them without a programme specific reference are usable as long as the BBC One logo doesn't change. Any of these:
