True. By then, if you have a DSA key and you want higher security, you will
have to create a signing subkey or something, and thus key bindings will
still have a 1024-bit security. Whereas starting out from RSA 4096 seems
like a good way to keep your signing key alife for a longer period. There
are already GnuPG versions that support sha-2 after all.

Also, from what people are saying, I induce that PGP doesn't come with
source, which is somewhat delicate on a cryptographic product.
