Is "Maintainer of bedevere" still accurate? I recall @brettcannon writing that he's moving away from maintaining infrastructure.

Yeah, I would argue I don't maintain Bedevere anymore.

[hugovk]

Okay, let's delete that too.

@brettcannon You're still an admin, right? Should you still be listed here? Would you like another role there, or an empty cell?

[Mariatta]

You can put me in as bedevere maintainer. Thanks.

[hugovk]

Thanks, updated!

[ezio-melotti]

@hugovk, do you want to update this PR after the devguide reorganization?

[hugovk]

@ezio-melotti Rebased!

It rebased cleanly with no conflicts, the re-org went well :)
