vim is not a single concrete editor - it's rather an abstract idea, and ideas do port (if done properly). But some substrates have poor foundation for porting, some have much more flexible base. Every vim plugin for major editors - VSCode, IntelliJ, Sublime, etc. have tons of deficiencies, partly because the platform itself might be prohibiting. In comparison, evil-mode in Emacs is absolutely great, in some cases it is even better than what Vim/Neovim have natively. And that's because of flexibility and malleability of the host platform.
