As said elsewhere in this thread, every feature you describe as "bloat" doesn't actually run until you tell it to. The features that make Visual Studio feel slow are things like IntelliSense, which is pretty goddamn core to the actual writing of code, not the fact that there's a visual designer for a few things. And code analysis is--wait for it--a pretty hard problem that perturbs a lot of electrons to do correctly, regardless of language or what particular program is kicking it off.
"But bloat!" is never an argument. Point to what it actually does to harm your experience if you want to formulate an argument; "it exists" is a nonsensical kvetch.
If you look at something like Atom with the Omnisharp plugin, it achieves everything I need from VisualStudio with a tiny fraction of the resources. Then again, if you're one of these programmers who write more code by dragging & dropping around a UI than actually typing (Microsoft has created a whole generation of these coders), then you probably need a lot of the VisualStudio bloat.
