Is this a bug or a feature

My standard Packer ist the ZIP Plugin (Alt+F5).
But after using once the Encrypt Plugin (CTRL+SHIFT+E) the next time I want to Pack (ALT+F5) the "Encrypt Plugin" is the selected Packer

I know, Encryption an ZIP-Archives are both "Packer", but I dislike the behavior mentioned above.
My suggestion: CTRL+SHIFT+E does not change the selected (standard) Packer
