The plugin shows debuff as icon on your raid frames (like GridStatusRaidDebuff does). It scans the debuff by name/id or debuff type. Debuff data must be provide by the layout (or copy from others). So this addon don't need to be updated frequently.
Since the rewrite, the new version is easier to use than the old one. If you find any problems just leave a comment.
My setup: https://github.com/yaroot/oUF_leaf/blob/master/layout/raid.lua
Git repo: https://github.com/yaroot/oUF_RaidDebuffs
.icon is not required
.SetDebuffTypeColor instead of .SetBackdropColor
Major rewrite, you might have to change some settings.
