for 3.1 we should get rid of them and have only one mode. it also makes writing the docs easier, when people can concentrate on one version of the docs instead of two or three.
I agree we should reduce as much as possible, but as said above, it is practically just like another global parameter.
there has always been changes in config file from one version to another. in 3.1, there should be only one mode and a documented list of changes that are needed from current K or S modes in order to get config working again.
