Yes, having it in there, but having it switched to off would be a great compromise: It would allow testing in a safe way.
Users could use it and experiment, to see if there are any bad side effects and if there are none, it could be turned on by default. Clutter is not a problem, as in the auto setting, it hides the settings and handles them for you. Also, you never ever need to touch, or for the matter, concern yourself with the tile settings for efficient fast rendering.
The initiative for including this in Blender Master is coming from my experiences in the last year, where I had the plugin active all the time, set on auto and doing both CPU rendering and GPU rendering, and varying resolutions, it has always given me ideal render times. I have even noticed that my benchmark times are slightly better when compared with the same hardware by others.
And the addon explains that very well: depending on the resolution, to get a perfect tile size, you have to change the tile size accordingly, both for CPU and GPU, which is a huge hassel. And who whips out a calculator to do that calculation every time?
Now who would I have to contact with this in order to start negotiations to get it included?
