I suspect that it is exported data that is broken, if
this --ignore-applied flag is needed for importing something
somebody exported.

I, however, am not 100% convinced --ignore-applied is too
dangerous to be useful in any conceivable use cases, at least
not yet.  For example, you might be cherry-picking a change from
a foreign branch with 'git-diff-tree -p other~45 | git apply',
where the current branch may have already aquired part of the
changes that foreign branch contains since 45 generations ago.
