There are some extremely opinionated assumptions underlying your question. VS isn't really bloated, given what it's trying to do- and in recent years it's been rock-solid stable. Visual Studio for Mac exists (old Xamarin Studio) and is coming along. And the engineering team has made its point on 64 bit clear that they don't believe it will bring the performance people like to say it will. But more importantly VS and VS Code are two different approaches- IDE vs TextEditor. The vast majority people would say C#, as a compiled language, is best in an IDE. Either way, I'm pretty confident in predicting that there is no way Visual Studio gets "dropped."
