This feature is quite a hot new feature in the 2.0 version. Backporting
flowspec into v1.x is virtually impossible due to Bird's internal architecture.

The 2.0 version is still in development; see the v2.0.0-pre0 tag in our
repository. There are several known bugs in flowspec, still unresolved,
but we're working on that.

Long story short, it is in progress.
