I choose to look at this a little differently.

An XML application using XSLT is so much better (faster load times, faster to write, easier to make correct) than a JavaScript application with a JSON api, that XML is basically a secret weapon.

I only care enough that it stays in browsers, but otherwise I'd prefer nobody know about it because it means less competition on things that matter (faster load times, faster to write, fewer bugs, etc). And I've got a half-baked JavaScript-based "renderer" I can finish in case some Google VP asshat goes looking for things to delete...
