There's nothing to "support" yet with PNaCl. It's still at the "we have no idea how to make this work" stage, last I checked.
And if it _could_ be gotten to work, you still haven't addressed why Mozilla should be willing to get on the Pepper "upgrade to keep up with all this unspecified stuff we're changing" treadmill.
It's not just scars from Flash and ActiveX; it's a distinct reluctance to bet everything on a technology you have 0 control over, and which one of your direct competitors controls completely. Now why would Mozilla be hesitant to do that? You tell me.
