Because you can revoke the old key and have all of it's signatures become
invalid. But, you cannot revoke this 'new' key that was created and passed
around as real using your compromised old key. It now has real signatures
that say 'I know for certain that this key belongs to this person'.

With dinstall a compromise is short lived and can be undone by erasing the
effected package. Creating a new key and getting people to sign it cannot
really be undone.
