Disagreement insofar as the direction of vim. Neovim choosing to go there on way on functionality they wanted to implement both ultimately enriched vim as some ideas found there way into vim proper and gave the community additional options.

Such splits aren't always handled well and value is lost when good ideas aren't merged back because of personal reasons and when contributors stop contributing because they are turned off by the drama. See libav vs ffmpeg.
