If you are not to use the key in gnupg, why make gnupg generate it in the first
place? Why not use the program with which you'll use the key to generate it? Or,
if the program does not offer this functionality, why not use openssl, which
provides this capability on purpose?

Were you to use the key both for gnupg and other systems, I would understand,
but doing things this way...?
