The major contributors are listed here: https://devuan.org/os/team/. Either they don't mention packagers specifically or they don't have a lot of them.
They didn't fork too many packages, so security handling should be fairly easy. They plan to offer support for a longer period than Debian. I don't think they'll be able to based on my experience contributing to a slightly bigger distribution (e.g. maybe 30-40 packagers) whom are lagging behind on security updates.
