I just found out those are added from within simple.el. But they look to me
more like a last minute hack before release although I am not sure.

What those e-v-l's do is pretty little and they don't belong there. If
there's a bug in, say, bbdb 2.29, should a new entry be added? After all
if a package is installed by a user, it is the user's responsibility.

Each entry could involve multiple e-v-l's. There's extra care that needs
to be taken.
