[gpg shows two keyid's for a DSS/DH key; pgp shows just the
primary keyid]

Because users need a keyid that identifies the key.  A second
keyid doesn't seem useful because  subkeys can be transitive. 
Multiple keyid's for a person's key can cause unnecessry
confusion.

Werner, what benefit is there to displaying the keyid for a
subkey?
