Keep in mind that no OpenPGP programs except very recent version of
GnuPG can even express weak signatures - and even GnuPG treats them as
cosmetic and does not interpret them differently. Think about that
for a second: no PGP user can even see what you are doing.

No. Getting more people in it in a strong manner makes it more
valuable. Adding weak signatures to it hurts it for everyone. You
don't need to add weak signatures to the web of trust for your robot
Your robot should not be part of the web of trust at all. It is a
(weak) CA. A CA is a different trust model than the web of trust. By
mixing the two, you hurt the web of trust without helping the CA model

"a little chaos in the meantime?" Wow, that's just what's needed to
get more people to adopt crypto. You know, for something that is
intended to make things simpler for Granny, we're now redesigning
trust models, modifying the keyanalyze reports, toying with massive
new infrastructure... maybe I missed it - when did things get simpler?
The goals and requirements for this thing should be just a little more
understood before we start redesigning a system that has worked quite
well for over 10 years and millions of messages.
