Bloat is relative and subjective. I've never used WebRTC, Pocket, or Loop/Hello, so I'd consider them bloat. On the other hand, I need to deal with PDFs fairly frequently, so it's convenient to have a browser that supports them. Someone else is going to have different requirements. I don't have a problem with that, but I'd prefer to have an option to disable or remove the features that I don't need or want.
