Obsoleted by Git now implementing its own trust model

so my elaborate workarounds of gpg's trust model are
rendered irrelevant and stupid.

No one ever used it in the intended manner.
Never --sign any Gpg key related to this project. --lsign it. The web of trust model was written around email, to protect against physhing and
spearphysh attacks. And who uses email for discussions and coordination these days?
That was useful in back in the days when when everything important was happening
on mailing lists like the cypherpunks mailing list. But even back in the day
the web of trust model had too many moving parts to be very useful. In
practice people only used Zooko identity, and Web of Trust was a cloud
of confusing complexity and user hostile interface on top of Zooko identity.
What gpg identity is primarily used for in practice is to make sure you
are getting the latest release from the same repository managed by the same person as
you got the previous release - which is Zooko identity, not Web of Trust
identity, and has no real relationship to email. Zooko identity is about
constancy of identity, Web of Trust is about rightful use of email
addresses. Web of trust was a true names mechanism, and today no one
speaks the truth under their true name.
Web of trust was designed for a high trust society - but in a high trust
society you don't need it, and in a low trust society, the name servers were
too vulnerable to enemy action, and died, leaving the Web of Trust user
interface in every installed copy of gpg a useless obstacle to people
trying to use gpg.
Never `sign` any Gpg key related to this project. `lsign` it.
