Maya and 3DS max has target camera ..it will be awesome if someone can implement it in blender.

I use the track to .....but sometimes it seems an extra unnecessary step

You have to explain it a bit more so everyone can understand it even if they dont use Maya..

And XSI and Houdini. Every other package has target lights and target cameras.

I really need this to be a thing. I'm a motion control operator and I can export so much useful data from Flair (the software I use to operate the robots) and unfortunately, I can't take full advantage of it in certain situations without an up vector target in Blender.
For those who aren't familiar, if your camera is "tracked to" a target, and it tilts past 90 degrees, it will flip upside down to keep the horizon level. I need it to not do that and the only way to achieve this is with an up vector target that tells the camera where up should be while still tracking to the target.
I can export a 3 node .fbx camera from Flair that is literally just 3 points (think of them as empties) that have their own coordinates moving through 3D space. I can 'copy location' of the camera and 'track to' the target but I need to be able to point to the up target on my current project to avoid having the camera rotate or twist.
Blender even puts a warning in the tooltip of 'track to' saying that it's prone to twisting artifacts. This could be easily solved with an up vector target.
Even if you don't think you have a use for this, eventually you will. Please upvote this!

Update: I believe I figured out how to make the camera behave as intended. If you start with 'damped track' constraint and select the target that you want the camera to look at, you can then add a 'locked track' constraint and select the up target. This seems to be doing everything I need right now. I don't think I will touch 'track to' anymore after this.

The track to constraint needs a way to control the UpVector of the camera, otherwise controlling the rotation of the camera is soooo hard.

Also miss it once in a wile, you can help yourself with using a "Track To" constraint:
