It seems that `PowerShellEditorServices` support only TCP protocol and cannot be ran as simply pipe (stdin/stdout) Language Service Server. It there any change (plan) to add stdin/stdout support, this will enable integration with more Editors/IDEs such as Sublime Text LSP and VIM-LSP. https://github.com/prabirshrestha/vim-lsp/issues/104 https://github.com/tomv564/LSP
