I get the no extra cost bit, but, seriously, a 7DII...how (considering Canon's extensive line up of models) is this considered a camera for video (in that people think it should have come with articulated screen and even touch screen)?
The 7DII is a sports and wildlife still camera...
If you brought one for video use, you probably got the wrong model...
Yes it is a is a sports and wildlife still camera..., so was the 7D in its day.
You get the video basically for free, a bit more software development using IP Canon probably already has. Some people use it for short clips of wildlife. TBH without a video peaking viewfinder it is a bit limited but better than nothing.
Of course it is no replacement for a proper pro HD video camera, but these do not come in at a budget price although the weight is a lot better these days, on top of that a solid video 'pod and damped head makes the real deal quite a lot of kit the manage, a dedicated still camera as well starts looking like a light accessory. This is why the feature is liked by some.
I can't see why you would object to something some people find useful, I can not see anyway the feature gets in the way of still camera use.
