I think the sensible default is already the default. The bug by default
is targeted at the development focus. But if one wishes to re-target the
bug to only affect a series which is not the development focus (say a
branch for the last LTS, for example), where the code has already
changed in the development focus, and therefore it does not exhibit the
bug, it is impossible to do so. There must always be a bug against the
development focus, even if it doesn't even contain code which is
affected by the bug. Instead, the only recourse is to mark it Invalid on
the development focus, which I don't think makes much sense.

If someone files a bug against a package in an LTS, and we want to link
that bug to the upstream project, we should be able to say that it
affects the series linked to the package in that LTS. If the bug then
also affects the current development focus (or perhaps any series in
between), then it can also be targeted to those series as well. But I do
firmly believe that it should be possible to target any bug to a single
series which is not the development focus.
