> the protocol has been adopted by Codenvy, who have added it to the next generation Eclipse IDE, Eclipse Che, as well as by Red Hat, who are working to publish a standalone language server for Java which can be consumed by any tool that utilizes the protocol.
> ... communities for programming languages like OmniSharp (C#), JSON, C++, xText, JavaFX, and R have made commitments to release language servers for their languages in the future.
Obviously we'll see if it actually happens, but at least other's are looking to support it.
It's early days but there are a number of organizations working on this. Today one such server was demoed at DevNation by RedHat - Java via the JDT.
omnisharp has already done this, at least specific to their stuff. granted, they are writing front-ends for each editor to integrate with a common language-server like described here, but its the same concept
Of course VS is old product and has some legacy we have to excuse, like COM, writing tons of boilerplate code just to show item in context menu, etc., but I mean philosophy of being friendly to everyone, regardless of underlying technology, is very important. For instance, writing language service, in C++ or C# only is a real limitation for some languages and prevents many languages of being integrated, so "Common Protocol for Languages" is right decision.
From another side, Visual Studio is very powerful in terms of customization. Creating virtual item hierarchy is easy (if we consider something can be easy when creating Visual Studio extension), so we have things like database project, with a lot of items, but no real files. I look forward to find similar possibilities in Visual Studio Code.
The most interesting part of this announcement was who they didn't mention: JetBrains. It will be interesting to see if they come on board with this.
