I've tried to reach out to keenerd a couple of times about dropping some packages of him such as geda-gaf (which lets us drop guile2.0, gtk2 in the future etc.). But I haven't heard back about these mails.
David has also tried to contact him about his key expiring and being unable to package after allan's master key will be revoked.
Keenerd did vote in recent TU proposals and still committed in May.  
So with this email I hope keenerd responds to the keyring issue and responds to the inquiries about his old packages.
