If Microsoft pivot VSCode to be a Visual Studio replacement then they will have a very serious problem. However as you say the refactorings are really good and the officially supported languages are supported really well. VSCode continues to feel like a cheap alternative as opposed to the software I want to use to solve a problem. It takes the place in my life of the editor I use when I need something more complicated than Vim but isn't really project work. The company seems to be doing very well and I read recently that the owners are now billionaires so I expect they'll be OK for this decade and probably the next as well. I expect the decline would be very slow if it happens at all.
