Why? It would make checking old mail archives more complicated. Further,
since a fix only requires a reordering of the sequence in which packets
are saved, is it really so difficult to fix it? I'll have a look at it
myself when I can find some time.

Most people, inclusing me, have stopped using it. However, I still have
a lot of mail archives from those days. Removing support would mean I
have to start using pgp 2 again to access them.
