The answer to this question may not be as simple as we think. What constitutes the difference between dungeons and raids currently is one is designed to familiarize you with mechanics and help you develop an affinity for the class you're playing; the other is test how well you perform, both as an individual and a teamplayer on a larger scale.. By the time you reach the current expansion of Normal Dungeon environments, you should fine tuning your spec's performance and adjusting for any new talents or changes to your spec as they come. In Heroic Dungeons, you're not only fine tuning, but you're also making your first steps toward progression to actual raiding; in short, gearing up to be raid-ready.
Enter the Raid Environment; During Normal and Heroic Dungeons, there was a loose observation and adherence to fight mechanics. As you progress through these difficulties, the mechanics become more impactful on your playstyle, forcing you to learn and adapt to the changing mechanics of the fight.
So what the hell does this have to do with Kara being a 5man dungeon or a raid?
It's about comparative value, difficulty vs. reward, and ultimately function.
Most importantly, what is the function of a 5-man Raid? It could be used for a lot of reasons; as OP mentioned, to give a smaller group of players a chance to reap rewards they would otherwise be unable to get in a larger raid environment due to time constraints, personal schedules, etc. But if that's the case, then what is the value of that gear? For it to qualify as "Mythic", said gear would have to be significantly greater than what a heroic instance might offer. However, if the gear is too powerful, say as how WoD Mythics can drop Heroic HFC quality gear, then it becomes a question of alternatives.
Would you rather face off against 24 other people in contest for a piece of loot or against 4 other people, 1 or 2 of which might share the same need for that specific loot?
Secondly, there's the value of the raid itself. if the value of the raid is higher than the current tier of raiding (minus 2pc/4pc Sets), then you're going to have people raiding Karazhan for superior quality gear and using the current raid tier as filler. Blizzard wouldn't allow that to happen, which means the value of the raid must be enough to encourage undergeared people to run it while providing the role of filler for heavily geared players. However, this is where the issue of difficulty versus reward steps in.
If the instance is TOO difficult for undergeared players, then they'll simply step into a normal/heroic raid and get their gear from there until they are ready handle 20man mythic content. If the instance is too easy, then there's no point.
Lastly, and this is the part that bothers me the most; timing.
7.1 will introduce Karazhan back into current content as a 5 man Mythic with a one week lockout. The timing suggests that this means the instance will be significantly harder than heroic dungeons, but not as difficult as the FIRST raid tier of the expansion which means all this effort into making Karazhan a new mythic 5man could result in the instance only being relevant for first part of the expansion. Once the next raid tier comes out, it would likely fall by the wayside for more powerful gear in environments that are either easier to attain or easier to get involved in.
Sorry for the long winded explanation, but that's my take on it.
TL;DR: Karazhan will be a nice filler in between heroic dungeons and actual raiding.
