That makes sense, cause it's true that the audio world -compared to design- is really plugin heavy. However, VSTs are mostly used by real pro users and the distribution the browser offers is not to be dismissed easily. Amateurs could get away with a few good plugins. When they are ready to make the transition, a native app or extension could be installed. But it would open an interesting door to quick editing something online, and even collaboration if integrated.
1. "VST" is often used as a synonym for plugins, but it absolutely is not. It's one particular plugin API/format.
2. If you're doing in-the-box composition, every sound you work with probably comes from a plugin. So the idea the plugins are mostly used only by pros is not really true. Synth choice is a hot topic and highly subjective issue, I don't think people would want to be heavily constrained there.
3. "quick editing" is already available online. Not much point with us trying to compete with that.
