An SVG doesn't need to support scripting. When you load an SVG through an <img> tag for example, no <script>s run either (only if you use <iframe>, <object>, or inline in HTML5). When you serve the SVG (or the HTML it is inlined in) with a CSP that doesn't allow inline scripts, no scripts run. It's totally possible to render an SVG without scripts (most SVGs do not contain scripts) and various mechanisms for this are already implemented in browsers.
