Thought it'd be neat to include the kill date of a boss on the actual boss kill progression tracker.
With the recent WoW easy-mode patch it allowed several lack luster guilds to progress to long time top server guilds in a matter of weeks versus their months and consumables.
This is something that's planned (also the number of kills), which is why the Raid Progression section has "destination" as a drop down - it's for tying it to the DKP portion.
