Should maintain a place of differenec within common usage and place an end there, so the coding of either don't place themselves anymore together they would be.
On ideas of interest of rather "porting" from or the other is an issue then this would be a limit of just its use more then, saying the use is the only one there.
More of ideas of a cross-platform again, but still. What seems to work the most might just be it. Usually in terms left with liimted cross-platform use, like saving formats of something the most. Can work with one format but can't save the other.
