It is not that complex - for symmetric encryption, only limited part is
used.  Try:

  $ gpg --list-packets aaa.txt.gpg
  :symkey enc packet: version 4, cipher 3, s2k 3, hash 2
        salt 071379daac57c0c1, count 65536 (96)
  gpg: CAST5 encrypted data
  :encrypted data packet:
        length: 32
  gpg: encrypted with 1 passphrase
  :compressed packet: algo=1
  :literal data packet:
        mode b (62), created 1309372527, name="aaa.txt",
        raw data: 4 bytes
  gpg: WARNING: message was not integrity protected

So there is actually four packets.  Also, you could drop the support of
compression.
