Bring assassination medals to campaign

One thing I’ve noticed for a while was that you do not get assassination medals in campaign. If course I’m talking about halo reach and 4, the only games in the collection that have the full third person animations. We get the medals in multiplayer and firefight, and spartan ops doesn’t display medals at all (though while we’re at it, might as well give us the option for that in spartan ops, even if there is no real scoreboard, though that’s a topic for another post), but why does the campaign only give the beat down medal (assassinations as they were pre-reach)? Is it an issue with the scoring system, to limit a possible exploit when it comes to clearing par score (considering the extra time it takes to execute, I don’t see the viability of leaning heavily on assassinations to build your score when you start losing your time multiplier)? Is it a bug that they never got around to fixing? Am I literally the only person to notice or bring this up?

I think I may have posted this to the wrong forum, meant to post to the general
