Engineering is always about trade-offs, and choosing a good balance in Chrome is what made it so popular.

If you really think the SVG feature was important and Chrome should support it, then lobby for it to be part of the standard and for other web developers to use it. But it's not a great example of Chrome pushing its whim on others.
