Seems like I would have to. As I have pointed out previously, it would
be difficult to contribute if one could not agree on the goal.

No, not really. If you can access the swap from remote, then you are
root, and therefore fully capable of replacing either the gnupg binary
itself, or reading the real memory on the machine - swap or not. If
you are not root, have access to the hardware, and are capable of
useing a screwdriver, you can remove the disk, replace the gnupg
binary and replace the disk with a trojan gnupg. Is there something
secret that I missed? I think I understood that you're afraid that
someone could read something that was swapped to disk, right? Sure,
you could crypt the swap, but really... I'd rather use a isolated
machine physically locked up, without network of any kind and a
grounded Farraday cage around it all to do my crypting then.

Of cource, it is in your right to say this. But really, I think
discussions about the goal of the development is important. I also
think I have a feeling of the reasons why not more people contribute

I will not upset you any further (at least not on this topic).
