After some consideration we have decided to remove[1] the 1k bit groups
from the moduli file. Vendors may want to consider doing this even for
older versions of OpenSSH (either by importing the new file, or by removing
them from the existing file) as it will result in stronger groups being
used for diffie-hellman-group-exchange-sha{1,256} transparently even if the
client prefers 1k bit groups (eg PuTTY and derivatives when using 128bit
ciphers).

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
