I know that there are several deep branches in a general attack tree,
but this is beside the point. Even if there are weaker spots, it seems sane to
try to keep the crypto part that GnuPG is responsible for strong.

Again, this is not an argument I can easily understand. But this is what I am
trying to do: Find a good chain of arguments, so that I and others can
understand and validate themselfs that the current choice of GnuPG's default
key length is a good one. Or come back with a better chain of arguments.
And then: Write them down, for more people to question and research them.
