No, it isn't. Everything is designed from the point of view of an
upgrade, and in this case "preserving local changes" of course must
include *not* to remove an unused conffile. It might contain important
work of the local administrator.
In case the maintainer knows that the presence of the old conffile would
be harmful, he has to do something about it (like moving it out of the
way), but he may still not silently delete it.
In case of a downgrade, this could in principle be done. But supporting
downgrades would increase both the work for maintainers and the
complexity of maintainer scripts by an insane amount, and is therefore
not supported. People who try unstable or even experimental packages
are expected to be able to perform a downgrade manually.
For example, you can purge nearly any package (unless it's essential, I
think) with --force-depends if you install the working, older version
immediately afterwards.
So essentially there is no bug, and there never was one. You just
expect too much from us.
