Well, one of them did, and Steve helpfully dropped me in it earlier in the week - I was granted write access to the debian-keyring. It's worth pointing out that while Steve did some prodding around this the process started quite some time ago; back in November James Troup (the other current keyring maintainer, and at the time the only one) contacted me regarding an offer I'd made to help out in whatever way I could. As a result I got involved in the keyring RT queue and did some basic triage and trying to point people in the right direction, where such help didn't require any keyring privileges. I also started thinking about how keyring maintenance could be shared in a trackable fashion. I made some suggestions to James and he was largely in favour with a few suggestions and wishlists.
I'll get into discussing exactly how it goes at a later point in time, but for the moment I want to get a better feel for the process and procedures to fine tune things. To that end I've been working my way through the keyring RT queue, and have removed quite a few keys of retired developers, as well as doing a handful of replacements for developers who'd lost or had their key compromised. There's still a few more tickets in progress and I'm trying my best to work through them in a timely manner - if you have an outstanding ticket and haven't heard from me then please do feel to ping it.
